The molecular formula is C₅H₁₀O₅.

EF = CH₂O

EF Mass = (12.01 + 2.016 + 16.00) u = 30.03 u

MF mass = 150 u

MF = (EF)_<em>n </em>

<em>n</em> = MF Mass/EF Mass = 150 u/30.03 u = 4.995 ≈ 5

MF = (CH₂O)₅ = C₅H₁₀O₅

Rory answered that absolute zero is 0°K. Is this answer correct? Explain why or why not.
Ierofanga [76]

Answer:

Yes, this answer is correct.

Explanation:

Absolute zero is -273.15 degrees celsius

T= Tc+273.15

T is the kelvin temperature

Tc is the temperature in degrees celsius

substitute;

T= -273.15 + 273.15

T=0 K

How many moles are there in 990 grams of sugar, C12H22011? (Sig Figs, do not
Nitella [24]

Answer:

Number of moles = 2.89 mol

Explanation:

Given data:

Number of moles of sugar  = ?

Mass of sugar = 990 g

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of C₁₂H₂₂O₁₁:

12× 12 + 22×1.008 + 16×11 = 342.2 g/mol

Number of moles = 990 g / 342.2 g/mol

Number of moles = 2.89 mol
