Answer:
Explanation:
You simply have to multiply it by the molar mass =
m = 50mol SnSO4 x 214.773 g/mol
m = 10.738 g SnSO4

Answer:
1,100 J.
Explanation:
- The amount of heat added to a substance (Q) can be calculated from the relation:
<em>Q = m.c.ΔT.</em>
where, Q is the amount of heat released from ethanol cooling,
m is the mass of ethanol (m = 50.0 g),
c is the specific heat of ethanol in the gas phase, since the T is cooled above the boiling point (c = 2.0 J/g °C),
ΔT is the temperature difference (final T - initial T) (ΔT = 79.0 °C – 90.0 °C = - 11.0 °C).
<em>∴ Q = m.c.ΔT</em> = (50.0 g)(2.0 J/g °C)(- 11.0 °C) = <em>- 1100 J.</em>
<em>The system releases 1,100 J.</em>
