Explanation:
Answer:
3.72
Explanation:
Given data:
Mass of object = 82.2 g
Volume of water = 25.0 mL
Volume of water + object = 47.1 mL
Density of object = ?
Solution:
Volume of object:
Volume of object = (Volume of water + object) - Volume of water
Volume of object = 47.1 mL - 25.0 mL
Volume of object = 22.1 mL
Density of object:
d = 82.2 g/ 22.1 mL
d = 3.72 g/mL
The molecular formula of a compound having the empirical formula C9H17O is calculated as below
(C9H17O)n =847.56
{(12 x9 + 1 x17 + 1 x16)}n= 847.56
147 n = 847.56
divide bot
h side by 147
n= 6
(C9H17O)6 therefore the molecular formula = C54H102O6
Answer:
oxygen is the most abundant element on the earth.
