Chemistry
1 answer:
atroni [7]3 years ago

Answer: 250 steps

Explanation:

The data we were given;

When Andrew walks 3 steps; Jeffrey walks 5 steps to catch up

That's is to say

Andrew's 3 steps = Jeffrey's 5 steps

Now Andrew's 150 steps = Jeffrey's X steps

So we have to find the number of steps (X) Jeffrey would have to take to catch up with Andrew.

3 = 5

150 = X

3X = 150 × 5

X = (150 × 5) / 3

X = 750 / 3

X = 250

Therefore Jeffrey would need 250 steps to catch up with Andrew.

Convert 6.7 x 1024 molecules of nitrogen dioxide into grams.
BlackZzzverrR [31]

Answer:

510 g NO₂

General Formulas and Concepts:

  • Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
  • Reading the Periodic Table
  • Writing Compounds
  • Using Dimensional Analysis

Explanation:

<u>Step 1: Define</u>

6.7 × 10²⁴ molecules NO₂ (Nitrogen dioxide)

<u>Step 2: Define conversions</u>

Avogadro's Number

Molar Mass of N - 14.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of NO₂ - 14.01 + 2(16.00) = 46.01 g/mol

<u>Step 3: Use Dimensional Analysis</u>

<u />6.7 \cdot 10^{24} \ molecules \ NO_2(\frac{1 \ mol \ NO_2}{6.022 \cdot 10^{23} \ molecules \ NO_2} )(\frac{46.01 \ g \ NO_2}{1 \ mol \ NO_2} ) = 511.901 g NO₂

<u>Step 4: Check</u>

<em>We are given 2 sig figs. Follow sig fig rules.</em>

511.901 g NO₂ ≈ 510 g NO₂
