How many moles are in 30 grams of H3PO4?
Answers
mass = 30g so;
30 = mol x GFM
To calculate the GFM, you require a data booklet or similar.
Mine tells me that the GFMs are:
H: 1 H₃ so 3 x 1 = 3
P: 31 P so 1 x 31= 31
O:16 O₄ so 4 x 16 = 64
GFM = 64 + 31 + 3 = 98
30 = 98 x mol
mol = 30 / 98
mol = 0.31 mol
Final answer:
To find the number of moles in 30 grams of H3PO4, divide the mass by the molar mass. In this case, there are 0.306 moles of H3PO4.
Explanation:
To determine the number of moles in 30 grams of H3PO4, we need to use the molar mass of H3PO4. The molar mass of H3PO4 is 98.0 g/mol.
We can use the following conversion factor to convert grams to moles: 1 mole = molar mass (in grams).
Therefore, the number of moles in 30 grams of H3PO4 is calculated as:
30 grams x (1 mole / 98.0 grams) = 0.306 moles of H3PO4.

Answer:
The answer is "Option D".
Explanation:
The entire ionic equation for all the substances, which are ionic compounds but are available in an aquatic is represented in the form with ions in the full ionic equation.
In the Net ionic equation, it doesn't have the particulate matter throughout the net ionic equations throughout the equations.
In the Spectator ions, it doesn't participate in interactions mostly on reaction and the material hand. From both sides, the very same ions are present.
The evenly balanced chemical formula is,
It is the separate organic compound that full ion formula will match the choice D.
Final answer:
The complete ionic equation for the reaction is 2K+ + 2OH- + 2H+ + SO42- → 2H2O + 2K+ + SO42-.
Explanation:
The complete ionic equation for the reaction 2KOH(aq) + H2SO4(aq) → 2H20(l) + K2SO4(aq) is:
2K+ + 2 OH- + 2 H+ + SO42- → 2 H2O(l) + 2 K+ + SO42-
The equation is balanced in terms of mass and charge by adding spectator ions (K+ and SO42-). The net ionic equation can be obtained by eliminating the spectator ions, leaving only the species that undergo a chemical change.

Explanation:
Matter in which molecules have strong force of attraction are held tight together. Therefore, to break this force of attraction strong force is required.
This type of matter is know as solid. Also, it is known that solid substances have definite shape and volume.
Thus, we can conclude that a substance with a definite shape and volume is a solid phase of matter.
