A compound has a molar mass of 86.0 g/mol and an empirical formula of C3H7 what is the molecular formula
zmey [24]
The formula for the molecular formula is molar mass/ empirical formula

So, the empirical formula of C3H7 is equal to C*3 + H*7 which is equal to 12*3 +  7. Then use the molecular formula = 86 / (12*3+7) = 2

Therefore, the molecular formula is 2 times the empirical formula which is C6H14.

A red sports drink contains Red 40 dye. A 5.4 mL aliquot of this sports drink was diluted to 25.0 mL with deionized water in a v
miskamm [114]

Answer:

84.0 ppm is the concentration of Red 40 dy in the original sports drink.

Explanation:

Concentration of red dye in sport drink before dilution C_1=?

Volume of the sport drink before dilution V_1=5.4 mL

Concentration of red dye in sport drink after dilution C_2=18.1 ppm

Volume of the sport drink after dilution V_2=25.0 mL

C_1V_1=C_2V_2( dilution )

C_1=\frac{C_2V_2}{V_1}=\frac{18.1 ppm\times 25.0 mL}{5.4 mL}

C_1=83.80 ppm\approx 84.0ppm

84.0 ppm is the concentration of Red 40 dy in the original sports drink.
