Density = mass / volume. So you'd write it out as D = 56g / 60.9cm^3, giving you 0.9195 g/cm^3.

Using Dimensional Analysis

Explanation:

Step 1: Define

Identify

[Given] 1.8 mol Mg

[Solve] atoms Mg

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

[DA] Set up: $\displaystyle 1.8 \ mol \ Mg(\frac{6.022 \cdot 10^{23} \ atoms \ Mg}{1 \ mol \ Mg})$
[DA] Multiply [Cancel out units]: $\displaystyle 1.08396 \cdot 10^{24} \ atoms \ Mg$

Step 4: Check

Follow sig fig rules and round. We are given 2 sig figs.

1.08396 × 10²⁴ atoms Mg ≈ 1.1 × 10²⁴ atoms Mg

What is the number of molecules present in 1.12 dm^3 of nitrogen gas at STP

Anuta_ua [19.1K]

Answer:

$\huge\boxed{\sf No.\ of\ molecules = 3 * 10\²\² \ molecules}$

Explanation:

Given Data:

Volume = v = 1.12 dm³ = 1.12 L

Density of nitrogen at STP = D = 1.25 g / L

Molar mass = M = 14 * 2 = 28 g / mol

Avogadro's Number = $\tt{N_{A}}$ = 6.023 * 10²³ mol⁻¹

Required:

No. of molecules = ?

Formula:

$\tt{No. \ of \ molecules = \frac{Density * Volume}{Molar\ Mass} * N_{A}}$

Solution:

No. of molecules = (1.25*1.12) / 28 * (6.023 * 10²³)

No. of molecules = ( 1.4 / 28 ) * 6.023 * 10²³

No. of molecules = 0.05 * 6.023 * 10²³

No. of molecules = 0.3 * 10²³

No. of molecules = 3 * 10²² molecules

$\rule[225]{225}{2}$

Hope this helped!
