Uma massa gasosa de um gas ocupa um volumede 30litros a 18 graus centigrados e pressa de 10 elevado a 5 pa. qual é a pressã do gas a 150 graus centígrados quando o volume de 20 litros

are there answer choices to this question? this seems like a question where you have options to choose from.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
