Answer:

16.8128 grams of sodium azide is needed

Explanation:

2NaN3 = 2Na + 3N2

molar mass of NaN3 =

2(11 + (7  \times 3) = 64

molar mass of N2

3(7 \times 2) = 42

moles of N2 =

moles=mass/R.F.M

16.55÷42 = 0.3940

mole ratio=

2NaN3 : 3N2

3 = 0.3940

2=?

0.394. \times 2 \div 3 = 0.2627

Mass of sodium azide =64×0.2627

=16.8126

Express the following numbers as decimals: (a) 1.52 x 10^-2, (b) 7.78 x 10^-8, (c) 1 x 10^-6, (d) 1.6001 x 10^3.
Alchen [17]

Answer :

(a) 0.0152

(b) 0.0000000778

(c) 0.000001

(d) 1600.1

Explanation :

Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example :

5000 is written as 5.0\times 10^3

889.9 is written as 8.899\times 10^{-2}

In this examples, 5000 and 889.9 are written in the standard notation and 5.0\times 10^3  and 8.899\times 10^{-2}  are written in the scientific notation.

(a) 1.52\times 10^{-2}

The standard notation is, 0.0152

(b) 7.78\times 10^{-8}

The standard notation is, 0.0000000778

(c) 1\times 10^{-6}

The standard notation is, 0.000001

(d) 1.6001\times 10^{3}

The standard notation is, 1600.1
