Answer: 0.664 moles and 65.1 grams EDMENTUM USERS
Explanation: From the equation, we know that 1 mole of calcium phosphate produces 2 moles of phosphoric acid (H3PO4). So, if we know how many moles of calcium phosphate are present in 103 grams of Ca3(PO4)2, we can find the corresponding number of moles of H3PO4 that are produced during the reaction.
The formula is Al2O<span>3. 2 aluminium and 3 oxygen

During diffusion substances move from the denser medium (meaning where there is more of the substance) to less dense medium (meaning where there is less of the substance).
Answer:
100.8 dm3
Explanation:
mol= volume
_______
molar volume
Simply transpose the formula
volume=mol x molar volume
4.5molx22.4 mol/dm3
= 100.8dm3
NB STP=22.4 dm3 or 22400 cm3
