The question ask for the percentage of the abundance of galium-69 where there is two isotopes of galium: the 69Ga and the 71Ga. The average atomic mass of gallium is 69.723 amu. So the formula would be <span>69.723amu=(%x)∗(68.926amu)+(1−%x)∗(70.025amu) and the answer to this is 1.58%</span>

A reaction at -6.0 °C evolves 786. mmol of sulfur tetrafluoride gas. Calculate the volume of sulfur tetrafluoride gas that is co

borishaifa [10]

Answer:

V of Sulfur tetrafluoride is 17.2 L

Explanation:

Given data;

T = -6°C = 267K [1° C = 273 K]

n = 786 mmol of SF4 which is 0.786 mol

P = 1 atm

from ideal gas law we have

PV = nRT

where n is mole, R is gas constant, V is volume

$V = \frac{nRT}{P}$ $V = \frac{0.786 mol \times 0.082 atmL/mol K \times* 267K}{1atm} = 17.2 L$

V of Sulfur tetrafluoride is 17.2 L
