Answer:
The main relationship between emerging scientific ideas and open-mindedness is that for many new ideas to be accepted a population has to have an open mind, otherwise the new ideas are rejected without thought.
Explanation:
We know, Given mass = Molar mass * Number of moles.
A.) <span>1.25 mol CaF</span>₂
Number of moles = 1.25
Molar mass = 78
So, Mass = 78 * 1.25 = 97.5 g
B.) 3.4 mol (NH₄)₂SO₄
Number of moles = 3.4
Molar mass = 132
Mass = 3.4 * 132 = 448.8 g
Hope this helps!
