Explanation:
it's one mole because the atomic mass is treated as molar mass and the atomic mass of strontium is 87.62 grams/mol
CaCl2
All of the other choices are elements
Explanation:
molarity=no. of moles of solute/solution in litres
6.17M=no. of moles of solute/9.4 L
6.17×9.4=no. of moles of solute
57.9 =no. of moles of potassium fluoride KF
no. of moles=given mass /molar mass
57.9=given mass/58
3358.2 g
F - 12.5
Cs - 87.5
F mass - 19
Cs mass - 132.91
