1.27g

Explanation:

Given parameters:

Number of moles of C₂₀H₄₂ = 4.52 x 10⁻³moles

Unknown:

Mass of the compound = ?

Solution:

The mole is a comfortable unit for measuring chemical substances.

number of moles = $\frac{mass}{molar mass}$

Molar mass of C₂₀H₄₂ = (12 x 20) + (1 x 42) = 240 + 42 = 282‬g/mol

Mass of the compound = number of moles x molar mass

= 4.52 x 10⁻³ x 282

= 1.27g

Caffeine is a compound found in some natural coffees and teas and in some colas. a. Determine the empirical formula for caffeine

andrey2020 [161]

Answer: The molecular formula will be $C_8N_4H_{10}O_2$

Explanation:

Mass of C= 49.47 g

Mass of N = 28.85 g

Mass of O = 16.48 g

Mass of H = 5.20 g

Step 1 : convert given masses into moles.

Moles of C = $\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{49.47g}{12g/mole}=4.12moles$

Moles of N = $\frac{\text{ given mass of N}}{\text{ molar mass of N}}= \frac{28.85g}{14g/mole}=2.06moles$

Moles of O = $\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{16.48g}{16g/mole}=1.03moles$

Moles of H = $\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{5.20g}{1g/mole}=5.20moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C = $\frac{4.12}{1.03}=4$

For N = $\frac{2.06}{1.03}=2$

For O = $\frac{1.03}{1.03}=1$

For H = $\frac{5.20}{1.03}=5$

The ratio of C : N: O: H = 4: 2: 1: 5

Hence the empirical formula is $C_4N_2OH_5$

The empirical weight of $C_4N_2OH_5$ = 4(12)+2(14)+1(16)+5(1)= 97 g.

The molecular weight = 194.19 g/mole

Now we have to calculate the molecular formula.

$n=\frac{\text{Molecular weight}}{\text{Equivalent weight}}=\frac{194.19}{97}=2$

The molecular formula will be = $2\times C_4N_2H_5O=C_8N_4H_{10}O_2$

How many oxygen atoms are present in 23.6 grams of aspartame?

olga55 [171]

The formula of aspartame is <span>C14H18N2O5.
From the periodic table:
molecular mass of hydrogen = 1 grams
molecular mass of carbon = 12 grams
molecular mass of nitrogen = 14 grams
molecular mass of oxygen = 16 grams

This means that:
molar mass of aspartame = 14(12)+18(1)+2(14)+5(16) = 294 grams
Therefore, each 294 grams of aspartame contains 5(16) = 80 grams of oxygen. To know number of grams of oxygen in 23.6 grams of aspartame, simply use cross multiplication as follows:
mass of oxygen = (23.6x80) / 294 = 6.42 grams</span>

A chemical reaction produces two new substances, and each product has a mass of 25 grams. What was the total mass of the reactan

hodyreva [135]

Well, according to the law of conservation of mass, the total mass of the reacting atoms must equal the total mass of the final rearranged products produced through the reaction. Assuming that both products are the only products produced, it would constitute the total matter produced, and since each product has a mass of 25 grams each. The total would be 50 grams. Thus the total mass of the reactants also would need to be 50 grams, as no matter is lost in a chemical reaction.
