A chemist mixes 96.2 g of chloroform with 31.2 g of acetone and 98.1 g of acetyl bromide. Calculate the percent by mass of each

stiv31 [10]

Answer:

42.6 % CHCl₃, 13.83 % C₃H₆O and 43.5 % CH₃COBr

Explanation:

This is a solution with 3 compounds:

96.2 g of CHCl₃

31.2 g of C₃H₆O

98.1 g of CH₃COBr

Total mass of solution is : 96.2g + 31.2 g + 98.1g = 225.5 g

Percent by mass is, the mass of the compounds in 100 g of solution

Let's prepare the rule of three

225.5 g of solution have ____ 96.2 g ___ 31.2 g _____98.1 g

100 g of solution would have ____

(100 . 96.2) / 225.5 = 42.6

(100 . 31.2) / 225.5 = 13.83

(100 . 98.1) / 225.5 = 43.5

Please help thank you! And how many significant figures does it have?

zheka24 [161]

Answer:

0.779 cube centimetres

Explanation:

density = mass divided by volume

$d=\frac{m}{v}$ rearrange the equation to solve for volume: $v=\frac{m}{d}$

plug in the corresponding values:

volume = 6.130 g / 7.87 (gcm^3)

the gs cancel, the answer will be 0.7789

we will round to three sig figs, since that's the lowest amount of figures in the given values: ~0.779 cm^3
