Calculate the amount of heat energy required to heat up 15.9 grams of ice from -4 °C to 14°C.
Stolb23 [73]

Answer:

581 Joules.

Explanation:

Using the formula;

Q = m × c × ∆T

Where;

Q = amount of heat absorbed (J)

m = mass of substance (g)

c = specific heat capacity (J/g°C)

∆T = change in temperature (°C)

According to the information provided in this question;

Q = ?

mass of ice = 15.9g

initial temperature = -4°C

final temperature = 14°C

Hence, ∆T = 14 - (-4) = 14 + 4 = 18°C

specific heat capacity (c) of ice in J/g°C = 2.03 J/g°C

Using Q = m × c × ∆T

Q = 15.9 × 2.03 × 18

Q = 32 × 18

Q = 581 Joules.

What is the molarity of a solution of 10% by mass cadmium sulfate, CdSO4 (molar mass = 208.46 g/mol) by mass? The density of the
Gekata [30.6K]

Answer:

a. 0.528 M ..

Explanation:

Hello!

In this case, since the given by-mass percent can be written as:

\frac{10gCdSO_4}{100g\ sol}

By using the density and molar mass of the solute, cadmium sulfate, we can compute the molarity, by also making sure we convert from mL to L of solution:  

M=\frac{10gCdSO_4}{100g\ sol}*\frac{1molCdSO_4}{208.46gCdSO_4} *\frac{1.10g\ sol}{1mL\ sol} *\frac{1000mL\ sol}{1L\ sol} \\\\M=0.528M

Thereby, the answer is a. 0.528 M .

Best regards.
