How many grams of solute are present in 615 ml of 0.630 m kbr?

Answers

molarity is the number of moles of solute in 1 L of solution
molarity of KBr solution is 0.630 M
this means that there there are 0.630 moles of KBr in 1 L solution 
then in 615 mL number of KBr moles are - 0.630 mol/L x 0.615 L = 0.387 mol
mass of KBr is - molar mass x number of moles 
KBr molar mass is 119 g/mol x 0.387 mol = 46.1 g
mass of KBr is 46.1 g

What does a mid ocean ridge record?

Answers

Explanation:

A mid-ocean ridge is a geological feature that records several important aspects of Earth's history and processes:

1. **Seafloor Spreading:** Mid-ocean ridges are where tectonic plates are moving apart. As new oceanic crust forms at these ridges through volcanic activity, it records the process of seafloor spreading. This process is a key component of plate tectonics, which explains the movement of Earth's lithospheric plates.

2. **Magnetic Reversals:** The seafloor at mid-ocean ridges contains bands of magnetic minerals that align with the Earth's magnetic field at the time the rock solidified. These bands provide a record of past magnetic field reversals, which is essential for understanding Earth's magnetic history.

3. **Geological History:** The rocks and formations found along mid-ocean ridges contain valuable information about the geological history of the ocean floor. This includes details about the composition of the Earth's crust and the minerals present in the oceanic lithosphere.

4. **Evidence of Hydrothermal Activity:** Mid-ocean ridges often host hydrothermal vent systems, where superheated water emerges from the seafloor. These vent systems record evidence of extreme environments and unique ecosystems that thrive in these conditions.

In summary, mid-ocean ridges record information about plate tectonics, magnetic field reversals, geological history, and hydrothermal activity, making them crucial sites for understanding Earth's dynamic processes and history.

Calculate the decrease in temperature when 2.00 L at 20.0 °C is compressed to 1.00 L.

Answers

We assume that this substance is in an ideal state. Then, we can use the ideal gas equation which is expressed as: PV = nRT. Comparing the first and second conditions of the substance, we can say that the number of moles and the pressure remains the same. We can solve the problem as follows:

P1V1 = n1RT1
P2V2 = n2RT2

Since P and n are the same for the conditions, we can combine the equations.

T1/V1 = T2/V2
20.0/2 = T2/1
T2 = 10.0 °C

There are two beakers that contain the same liquid substance at the same temperature. The larger beaker is 1,000ml and the smaller beaker is 100ml. How does the thermal energy of the liquid in the larger beaker compare to the thermal energy of the liquid in the smaller beaker?A. The liquid in the larger beaker has the same amount of thermal energy as the liquid in thesmaller beaker.
B. The exact volume of liquid in each beaker must be known to compare the thermal energyof the liquids.
C. The liquid in the larger beaker has less thermal energy than the liquid in the smaller beaker.
D. The liquid in the larger beaker has more thermal energy than the liquid in the smaller beaker.

Answers

Answer:

Answer choice B

Explanation:

Since you do not know the volume of the liquid in each beaker, the one in the smaller beaker could have more substance and therefore more thermal energy. If they had the same amount of substance, then the more voluminous one would radiate faster. However, since you do not know this, there is no way to tell. PM me if you have more questions. Hope this helps!
