vice versa: atoms are elements, so elements are made of atoms specifically 1 atom or multiple of the same kind
First calculate the number of moles of CaBr2 given the
molar mass of 199.89 g/mol.
moles CaBr2 = 0.9182 g / (199.89 g / mol) = 4.60 x 10^-3
mol
We see that each CaBr2 contains only 1 mole of Ca, so the
moles of Ca is also:
moles Ca+ = 4.60 x 10^-3 mol
So the molarity of this is:
Molarity Ca+ = 4.60 x 10^-3 mol / 0.500 L
<span>Molarity Ca+ = 9.19 x 10^-3 M</span>
Answer:
Fundamental Units are the units which are independent of any other unit.
They do not depend on any other physical quantity for their measurements .
Derived Units are derived from Fundamental Units.
They are are products and/or ratios of the fundamental quantities that exist in a system of units.
Explanation:
M/sec = 112 km / 1 hr / 1 min / 1000 meters
hr / 60 min / 60 sec / 1 km
So the answer is = 31.1 meters/sec
