B, D and E
Explanation:
conversion factors
1c = 8oz
1pt = 2c
1qt = 2pt
For A and B
ounces to cup = 160/8 = 20c
cup to pints = 20c / 2c = 10pt
pint to quarts = 10pt/2pt = 5qt
B applies as four 1-quart and two 1-pt = 5 1-quart
Considering C
4 8oz = 32oz
160-32 = 128oz /8 = 16c/2 = 8pints C does not apply
considering D
8 * 8 = 64oz
160 - 64 = 96oz/8 = 12c/2 = 6pt/2 = 3qt
So D applies
E applies
Answer:
0.81mole
Explanation:
Given:
Volume of carbon monoxide = 18dm³
Unknown
Number of moles of carbon monoxide = ?
Solution:
To solve this problem;
1 mole of any gas at rtp occupies a volume of 22.4dm³
So;
x mole of carbon monoxide will occupy a volume of 18dm³ at rtp
22.4x = 18
x = = 0.81mole
