Answer:
b
Explanation:
because motions make things hotter
Answer:
198g
Explanation:
Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol
Number of mole of CO2 = 4.5moles
Mass of CO2 =?
Mass = number of mole x molar Mass
Mass of CO2 = 4.5 x 44 = 198g
Answer: 7.88375g
Explanation:
Here is the dimensional analysis table
7g O2 | 1 mol O2 | 2 mol H2O | 18.02 g H2O
| 32 g O2 | 1 mol O2 | 1 mol H2O
You use grams to convert to moles of O2, then use that to find grams of H20
