Explanation:

Mass of the Earth is equal to,

$m=5,970,000,000,000,000,000,000,000\ kg$

Any number can be written in the form of scientific notation as :

$N=m\times 10^n$

m is the real number

n is any integer

Mass of the earth can be written in the form of scientific notation as :

$m=5.97\times 10^{24}\ m$

Here,

m = 5.97

n = 24

Hence, this is the required solution.

Answer from: challenggirl

For the given value of mass of Earth, the value of constants m and n are 5.970 and 24 respectively.

Given data:

The mass of Earth is, M = 5,970,000,000,000,000,000,000,000 kg.

The scientific notation is a mathematical approach of expressing any quantity in terms of $m \times 10^{n}$ . This approach is used for the simplification of numerical data and calculations involved in the outcome of these data.

Here,

m and n are the notational constants.

Solving the given value as,

$M=5,970,000,000,000,000,000,000,000\\\\M=5,970 \times 10^{21}\\\\M=5.970 \times 10^{24}$

From the above result,

$m = 5.970\\n=24$

Thus, we can conclude that for the given value of mass of Earth, the value of constants m and n are 5.970 and 24 respectively.

Answer from: Quest

1.the balanced chemical equation is as below

cu + 2 ag(no)₃ → cu(no₃)₂ +2 ag

2.the much silver produced is 50.9 g

step 1: find the moles of cu

moles = mass÷ molar mass

from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236 moles

step 2: use the mole ratio to determine the moles of ag

from equation above cu: ag is 1: 2

therefore the moles of ag =0.236 moles x 2/1 =0.472 moles

step 3: find the mass of ag

mass = moles x molar mass

from periodic table the molar mass of ag =107.87 g/mol

mass = 0.472 moles x 107.87 g/mol = 50.9 g

3. the much silver collected worth is 1.797 oz

convert 50.9 g to oz

that is 1 gram = 0.0353 oz

50.9 grams =? oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1 gram} =1.797 oz
