An object with a density of 3.7kg/m^3 has a mass of 2.5g. What's the volume in mL?

1 answer:

5 0

$d=3,7\frac{kg}{m^{3}}=3,7\frac{1000g}{1000000mL}=0,0037\frac{g}{mL}\\
m=2,5g\\\\
d=\frac{m}{V} \ \ |*V\\
dV=m \ \ |:d\\
V=\frac{m}{d}=\frac{2,5g}{0,0037\frac{g}{mL}}\approx 675,68mL$

Answer:

The answer is " $= 0.078 \ kg \ H_2$ ".

Explanation:

calculating the moles in $CH_4 =\frac{PV}{RT}$

$=\frac{(0.58 \ atm) \times (923 \ L) }{ (0.0821 \frac{L \cdot atm}{K \cdot mol})(232^{\circ} C +273)}\\\\=\frac{(535.34 \ atm \cdot \ L) }{ (0.0821 \frac{L \cdot atm}{K \cdot mol})(505)K}\\\\=\frac{(535.34 \ atm \cdot \ L) }{ (41.4605 \frac{L \cdot atm}{mol})}\\\\= 12.9 \ mol$
