Answer:
Volume in L = 0.028 L
Explanation:
Given data:
Mass of copper phosphate = 27.6 g
Molarity solution = 6.03 M
Volume of solution = ?
Solution:
First of all we will calculate the number of moles of copper phosphate.
Number of moles = mass/molar mass
Number of moles = 27.6 g/ 159.61 g/mol
Number of moles = 0.17 mol
Volume of solution:
Molarity = number of moles / volume in L
By putting values,
6.03 M = 0.17 mol / volume in L
Volume in L = 0.17 mol / 6.03 M
Volume in L = 0.028 L
It is impossible to run 15 miles an hour
I think
Hope this helps :D
Answer:
K2CrO4
Explanation:
To find the empirical formula, we need to divide each element by its atomic mass. The atomic masses of potassium, chromium and oxygen are 39.0983, 51.9961 and 15.999 respectively. We make the divisions as follows:
K = 1.04/39.0983 = 0.027
Cr = 0.70/51.9961 = 0.013
O = 0.86/15.999 = 0.054
We now divide by the smallest which is the number of moles of the Chromium
K = 0.027/0.013 = 2
Cr = 0.013/0.013 = 1
K = 0.054/0.013 = 4 approximately
The empirical formula is thus:
K2CrO4
1. Change in color
2. Formation of bubbles
3. Formation of a precipitate
4. Begins to make an odor
12) Solubility
Solubility is the ability to be dissolved, especially in water.
