What is the molarity of a solution that contains 30 grams of naoh in 500 milliliters of solution?

Answers

Molar mass NaOH = 39.997 g/mol

number of moles solute:

n = mass of solute / molar mass

n = 30 / 39.997

n = 0.00075 moles of NaOH

Volume in liters:

500 mL / 1000 => 0.5 L

Therefore :

M = moles of solute / volume ( L )

M = 0.00075 / 0.5

M = 0.0015 mol/L

Answer: 1.5 M

Isn't this false? For the industrial production of indigo carmine, a blue food colouring additive, a synthetic process with an E-factor of 17.4 produces less waste than a synthetic process with an E-factor of 3.0.

The answer I got was False, is this correct?

Answers

Answer: yes it is false

Explanation:

The statement is false. A synthetic process with a lower E-factor produces less waste than a process with a higher E-factor.

The E-factor is a measure of the waste generated during a manufacturing process. It is calculated by dividing the total mass of waste produced by the mass of the desired product. A lower E-factor indicates that less waste is generated per unit of product.

In this case, the synthetic process with an E-factor of 3.0 produces less waste than the process with an E-factor of 17.4. This means that the process with an E-factor of 3.0 is more efficient in terms of waste reduction.

How many moles of carbondioxide are produced when 0.2mol of sodium carbonate react with excess hydrovhloric acid

Answers

Answer:

0.2 moles of CO₂ are produced

Explanation:

Given data:

Moles of CO₂ produced = ?

Moles of Na₂CO₃ react = 0.2 mol

Solution:

Chemical equation:

Na₂CO₃ + 2HCl → 2NaCl + CO₂ + H₂O

Now we will compare the moles of CO₂ with Na₂CO₃ .

Na₂CO₃ : CO₂

1 : 1

0.2 : 0.2

Thus, 0.2 moles of CO₂ are produced.

Convert 50g of calcium carbonate, CaCO3, into moles

Answers

Answer:
Moles = 0.5 mol

Solution:

Moles is related to mass as follow,

Moles = Mass / M.mass ----- (1)

Where;
Mass = 50 g

M.mass = Ca (40) + C (12) + O₃ (16)₃ = 100 g/mol

Putting values in equation 1,

Moles = 50 g ÷ 100 g.mol⁻¹

Moles = 0.5 mol

The image formed by a lens may be real or virtual. The image formed by a lens is always virtual.

Answers

There are types of lens; concave and convex lens.
The concave lens is a lens which has an inward curve in the middle, that is, the edges of the curve are thicker than the center of the lens, because of this, any light that enter the lens will spread out [diverge]. An image will look smaller and upright when viewed by a concave lens. Image formed by concave lens are usually VIRTUAL.
A concave lens will produce a real image ONLY if the object is located beyond the focal point of the lens.
A convex lens is a converging lens, this is because, the center of the lens is thicker than its edges. Any ray of light that passes through the lens will converge at the middle of the lens at point called principal focus. A convex lens produce a VIRTUAL image when the object is placed infront of the focal point. The virtual image formed is always magnified and upright.

The image formed by any lens like concave and convex may be real or virtual.

How many types of lens are present?

Mainly two types of lens are present and that are concave lens also known as divergent lens and convex lens, also known as convergent lens.

Any light passing through the lens will disperse [diverge]. When viewed through a concave lens, an image seems smaller and more upright. Concave lenses frequently produce VIRTUAL images and concave lens will produce a real image only if the object is located beyond the focal point of the lens.
Any beam of light passing through the lens will converge in the lens's center, known as the main focus. When an object is placed in front of the focal point, a convex lens produces a VIRTUAL image. The resulting virtual picture is constantly amplified and oriented vertically.
