Answer:
150.016 grams
Explanation:
molar mass of cH3OH=12+4+16 =32 u
mass = nu. of moles × molar mass
mass= 0.2344 × 32 =7.5008 gm÷ 0.0500 = 150.016 gm
Hello!
I don't know a lot of this but after doing just a bit of research I think the answer is either A. or C. but I think it is A.
Hope it helps?
Fire is actually a chemical reaction. It's an oxidation reaction to be specific. When wood gets hot enough (the part of the wood that is burning) the large hydrocarbons break down to charred solids and a gas. The gas is what reacts with oxygen in the atmosphere to produced light, CO2 and H2O.
X4O10
Let molar mass of X be y
molar mass = 4y + 10 x 16 = 4y+160
so, moles = 85.2 / (4y+160)
Moles of oxygen = 10 x [85.2 / (4y+160) ]
Mass of oxygen = 16 x 10 x [85.2 / (4y+160) ]
which is 48.0
so, 48 = 16 x 10 x [85.2 / (4y+160) ]
Solve the equation to get y.
y = 31
What are you asking? Id love to help but cant without proper information
