Answer:

1.90 L

Explanation:

Using Boyle's law

${P_1}\times {V_1}={P_2}\times {V_2}$

Given ,

V₁ = 595 L

V₂ = ?

P₁ = 1.00 atm

P₂ = 55.0 atm

Using above equation as:

${P_1}\times {V_1}={P_2}\times {V_2}$

${1.00}\times {595}={55.0}\times {V_2}$

${V_2}=\frac{{1.00}\times {595}}{55.0}\ L$

${V_2}=1.90\ L$

<u>The volume would be 1.90 L.</u>

What is the empirical formula of a compound consisting of 29.6% oxygen and 70.4% fluorine by mass?

Rainbow [258]

O1Fl2

1. Assume an 100g sample, so the percentage will stay the same

2. Covert each element into their molar mass
29.6/16.00=1.8 mols of O
70.4/19.00=3.7 mols of Fl

3. Divide both by the smallest value of mol
1.8/1.8=1 O
3.7/1.8=2 Fl

4. Write the empirical formula:
O1Fl2
