How many moles of NaCl are in 2,719 mL of a 6.32 M solution?

Mademuasel [1]

Answer:

17.18 moles of NaCl are in 2,719 mL of a 6.32 M solution.

Explanation:

$Molarity=\frac{\text{Moles of substance}}{\text{Volume of solution in L}}$

We have:

Molarity of the NaCl solution = 6.32 M

Volume of the NaCl solution = 2,719 mL =2,719 × 0.001 L= 2.719 L

1 mL = 0.001 L

Let the moles of NaCl be n.

$6.32 M=\frac{n}{2.719 L}$

$n=6.32M\times 2.719 L=17.18 mol$

17.18 moles of NaCl are in 2,719 mL of a 6.32 M solution.

Answer:

0.3936 J/gC

Explanation:

using the formula: q=mcΔt

q= 7032J

m=812g

ΔT = 22C

plug in and solve:

7032=(812)(c)(22)

c=7032/(812)(22)

c=0.39 J/gC
