Answer:
490kpa
Step-by-step explanation:
V1 = 70ml and P1 = ? kpa
V2 = 15ml and P2 = 105kpa
if 15ml will give me 105kpa
then how many times is 70ml greater than 15ml
70/15 = 4.6667
then multiply it by 105kpa
4.6667 * 105 = 490kpa
meaning that if 15ml will give me 105kpa
then 70ml which is (15*4.667) will give 490kpa
