What is room temp?
25C
What is room pressure?
1atm
1 __ of any __ at room temp (25C) and pressure (1atm) has a vol. of __
mole, gas, 24dm3
Thus, Vgas = n x __
24
1dm3 = ~__L or __kg
1, 1
1dm3 = __cm3
1000
1cm3 = __dm3
.001
The volume of 4.00mol of O2 at room temp & pressure is:
__ x 24 = 96__
4, dm3
State the formula of percentage yield.
actual yield/theoretical yield x 100
If actual yield was 15g and theoretical yield was 19g, what is the % yield?
% yield = __/__ x __ = 79%
15/19 × 100
Why is actual yield not 100%?
1. i__ reactions (some r__ don’t react to form p__)
incomplete, reactants, products
Why is actual yield not 100%?
2. __ losses during e__ e.g. during pouring
practical, experiment
Why is actual yield not 100%?
3. s__ reactions (unwanted reactions compete with d__ reactions)
side, desired
