We assume that the volume of the molecules themselves in a gas sample is negligible compared to the bulk volume of the gas sample: this helps us to explain why gases are so compressible.
Answer:
89.6 liters
Explanation:
A STP (standard temperature and pressure) ONE mole of any idea gas will occupies 22.4 liters. So,...
4 moles x 22.4 L/mol = 89.6 liters
Kilometers, Meters and centimeters if metric
Feet, inches, yards and miles if customary ( u.s.)
Answer:
219.15 grams
Explanation:
What is the mass of 3.75 moles of NaCI? ( Na= 22.99g/mol, CI= 35.45 g/mol)
Mole of Na = 22.99g
Mole of Cl = 35.45g
For NaCl we have ratio of 1:1, so we have 1 Na for every Cl
So we just add the two together to get the molar mass of NaCl which is
22.99 + 35.45 = 58.44g/mol
And we know we have 3.75 moles of NaCl so we multiply that by the molar mass of NaCl to get our answer
3.75 x 58.44 = 219.15grams
