1. Well, standard pressure just means 1 atm. The temperature and the moles of the gas will not change. The things that change in this problem are the pressure and volume. Since you already know the volumes, you can solve this problem using Boyle's law:
P1V1 = P2V2
P1 = 1 atm
V1 = 1L x 1000mL/1L = 1000mL
P2 = ?
V2 = 473 mL.

Rearrange the equation for what you want to get, P2:
P2 = P1V1 / V2
P2 = 1 atm x 1000mL / 473mL
P2 = 2.11atm

2. P1V1=P2V2
P1=1atm, V1=1000ml, V2=473ml
P2=P1V1/V2
=1atm*1000ml/473ml
