Question

a sample of a compound consisting only of copper and sulfur contains 88.39g of metal and 44.61g of nonmetallic. How many grams of copper are in a 5264kg sample of the compound? How many grams of sulfur? Enter your answers in scientific notation.

Answer 1

(88.39 / (88.39 + 44.61) ) x (5264000) = answer for copper grams

(44.61 / (88.39 + 44.61)) x (5264000) = answer for sulfur grams

Sulfur is a non-metal used to make paper, number 16 on periodic table.

Answer 2

Answer: The mass of copper is
`3.50* 10^6g` and mass of sulfur is
`1.77* 10^(6)g`

Step-by-step explanation:

We are given:

Mass of metal (Copper) = 88.39 g

Mass of non-metal (Sulfur) = 44.61 g

Mass of compound = 88.39 + 44.61 = 133 g

Mass of given sample = 5264 kg = 5264000 g (Conversion factor: 1 kg = 1000 g)

To calculate the mass of copper present in 5264 kg of sample, we use unitary method:

In 133 g of sample, the mass of copper is 88.39 g

So, in 5264000 g of sample, the mass of copper will be =
`(88.39)/(133)* 5264000=3498383.2g=3.50* 10^(6)g`

To calculate the mass of sulfur present in 5264 kg of sample, we use unitary method:

In 133 g of sample, the mass of sulfur is 44.61 g

So, in 5264000 g of sample, the mass of sulfur will be =
`(44.61)/(133)* 5264000=1765616.8g=1.77* 10^(6)g`

Hence, the mass of copper is
`3.50* 10^6g` and mass of sulfur is
`1.77* 10^(6)g`
