Hello!
The volume of the gas when its pressure is increased to 880 mm Hg is
88,64 mLThis question can be easily answered using the
Boyle's Law, which states that as pressure increases, the volume is lower. It can be expressed in a mathematical way as follows:
So, from this equation we can clear V₂ to find the volume at 880 mm Hg:
Have a nice day!
The volume of 0.160 m Li2S solution required to completely react with 130 ml of 0.160 CO(NO3)2 is calculated as below
write the reacting equation
Co(NO3)2 + Li2S = 2LiNO3 + COS
find the moles of CO(NO3)2 = molarity x volume
= 130 ml x 0.160=20.8 moles
since the reacting moles between CO(NO3)2 to LiS is 1:1 the moles of LiS is also 20.8 moles
volume of Lis is therefore = moles of Lis/ molarity of LiS
= 20.8/0.160 = 130 Ml
