because,
1kg = 1000g
so
198g = 0.198g
divide it by 1000 to get kg
The answer is D
Calcium has two electrons in its outer energy shell
Answer:
8.822 × 10¹³ g Co
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
- Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
Explanation:
<u>Step 1: Define</u>
9.015 × 10³⁵ atoms Co
<u>Step 2: Identify Conversions</u>
Avogadro's Number
Molar Mass of Co - 58.93 g/mol
<u>Step 3: Convert</u>
<u />
= 8.82189 × 10¹³ g Co
<u>Step 4: Check</u>
<em>We are given 4 sig figs. Follow sig fig rules and round.</em>
8.82189 × 10¹³ g Co ≈ 8.822 × 10¹³ g Co
Answer: The direction will be the opposite direction in the balanced force. The object stays at rest in the balanced force. The speed of the object continues to move in the same speed. And the net force acting will be zero.
