A 0.9182 g sample of CaBr2 is dissolved in enough water to give 500 ml of solution. what is the calcium ion concentration in thi
Nataly_w [17]

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>

Suppose there is 0.63 g of HNO3 per 100 mL of a particular solution. What is the concentration of the HNO3 solution in moles per
Vadim26 [7]

Answer:

There are 0.09996826 moles per liter of the solution.

Explanation:

Molar mass of HNO3: 63.02

Convert grams to moles

0.63 grams/ 63.02= 0.009996826

Convert mL to L and place under moles (mol/L)

100mL=0.1 L

0.009996826/0.1= 0.09996826 mol/L

patriot [66]
The Largest. There are 17 bodies in the solar system whose radius is greater than 1000 km. The composite above shows the Sun and the 5 largest planets at a scale of 3200 km/pixel. (Earth<span> is the tiny spot between Jupiter and the Sun) so the sun is the largest body in our solar system. hope this helped! ^^</span>
