To get the percent mass of calcium, first let us compute for the total mass:

total mass = 2.89 g + 5.11 g

total mass = 8 g

So the percent mass of calcium is:

% calcium = (2.89 / 8) * 100% = 36.125%

6.0L of a gas exert a pressure of 2.5 atm. When the pressure is increased to 10.0atm what is the new volume of the gas

jeka57 [31]

Answer:

<h2>1.5 L</h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we are finding the new volume

$V_2 = \frac{P_1V_1}{P_2} \\$

From the question we have

$V_2 = \frac{6 \times 2.5}{10} = \frac{15}{10} = \frac{3}{2} \\$

We have the final answer as

<h3>1.5 L</h3>
