<h2>
Answer:</h2>
We will need to know Avogadro's number and the molar mass of sucrose for this problem to do dimensional analysis.
- Avogadro's number: 6.022 × 10²³ molecules
- Molar mass of sucrose: 342.2965 g/mol
250g ×
×
= 4.398 molecules
There are <em>4.398 sucrose molecules </em>in 250 grams of sucrose.
10 because you divide 200 by 20
Hg = (3.2 : 4.2) x 100% = 76.19%
O = (1 : 4.2) x 100% = 23.81%
Answer:
metallic bonding is the bond form between two or more metal elements or between metal element and the other group elements
