P x V = n x R x T
1.00 x V = 3.50 x 0.082 x 273
1.00 x V = 78.351
V = 78.351 / 1.00
V = 78.351 L
Answer:

2. 6
3. 3
Explanation:
1. Reactans on left side, products on right side
2. 3 x 2
3. 3
Atoms bond to form molecules: Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed.
A is the answer to this question. Thank you.
Molar mass
Ca₃(PO₄)₂ = 310 g/mol
1 mole -------------------> 310 g
2.3x10⁻⁴ mole ---------> ?
m = 2.3x10⁻⁴ * 310 / 1
m = 0.0713 g
hope this helps!
