Question

how many moles of gass will a 486 ml flask hold at 10 celsius and 500 torr?

Answer 1

@iPwnBunnies can u help with one more plz

Answer 2

its gas law

Answer 3

use the formula PV = nRT
u want to find mole so u meed to make 'n' as subject
n = PV/RT
P= 500 torr (convert to Pascal) so it'll be around 66 661.2 Pa
V= 485 ml (convert to m^3) so it'll be 485/1000 000= 4.85*10^-4
R (is a constant)= 8.31
T= 10 Celsius (convert to Kelvin) so it'll be 10+273= 283 K
and now substitute all these into the formula and u'll get the answer

Answer 22

@Karina1 you have to use SI system units here, that's why you need to convert those units to appropriate units from SI system
when you use SI system you don't need to worry about units because you will surely get it right
