Answer:
621.2090000000001 grams
Explanation:
1 moles Calcium to grams = 40.078 grams
15.5*40.078 = 621.2090000000001 g

Answer:
The answer to your question is B
Answer:
1.62 L.
Explanation:
- To solve these problems, we can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm (P = 101.3 kPa/101.325 ≅ 1.0 atm) .
V is the volume of the gas in L (V = ??? L).
n is the no. of moles of the gas in mol.
R is the general gas constant (R = 0.082 L.atm/mol.K),
T is the temperature of the gas in K (T = 34.0 °C + 273.15 = 307.15 K).
The volume of the gas = nRT/P.
P = 1.0 atm,<em> V = ??? L</em>, R = 0.082 L.atm/mol.K, n = mass/molar mass = (1.8 g)/(28.0 g/mol) = 0.0642 mol.
<em>∴ V = nRT/P</em> = (0.0642 mol)(0.082 L.atm/mol.K)(307.15 K)/(1.0 atm) = <em>1.62 L.</em>
