$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve for x ~

$\qquad \sf \dashrightarrow \:4x - 16 = 64$

$\qquad \sf \dashrightarrow \:4(x - 4) = 64$

$\qquad \sf \dashrightarrow \:(x - 4) = 64 \div 4$

$\qquad \sf \dashrightarrow \:x - 4 = 16$

$\qquad \sf \dashrightarrow \:x = 16 + 4$

$\qquad \sf \dashrightarrow \:x =20$

A 1.50 liter sample of dry air in a cylinder exerts a pressure of 3.00 atmospheres at a temperature of 25oC. Without change in t

cricket20 [7]

The answer is 4.5 l

To calculate this, we will use the Boyle's law using constant k, pressure P, and volume V:

PV = k

We can forget temperature since it is constant.

We have:

P1V1 = k

P2V2 = k

So, P1V1 = P2V2

P1 = 3 atm

V1 = 1.5 l

P2 = 1 atm

V2 = ?

_____

P1V1 = P2V2

3 atm * 1.5 l = 1 atm * V2

4.5 atm/l = 1 atm * V2

V2 = 4.5 atm l / 1 atm

V2 = 4.5 l
