There are seventeen key nutrients essential for bone health. The ideal intake of calcium is approximately 1.75 g per day. How ma

baherus [9]

Answer:

2.63×10²² atoms

Explanation:

From the question given above, the following data were obtained:

Mass of calcium (Ca) = 1.75 g

Number of atoms of calcium (Ca) =?

From Avogadro's hypothesis,

1 mole of Ca = 6.02×10²³ atoms

Recall:

1 mole of Ca = 40 g

Thus,

40 g of Ca = 6.02×10²³ atoms

Finally, we shall determine the number atoms in 1.75 g of calcium. This can be obtained as follow:

From Avogadro's hypothesis,

40 g of Ca = 6.02×10²³ atoms

Therefore,

1.75 g of Ca = 1.75 × 6.02×10²³ / 40

1.75 g of Ca = 2.63×10²² atoms

Thus, 1.75 g of Ca contains 2.63×10²² atoms.

How many moles of HCl are there in 75.0 mL of 0.325 M HCI?

dangina [55]

Answer: The moles of HCl are 0.0244

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=\frac{n\times 1000}{V_s}$

where,

n = moles of solute = ?

$V_s$ = volume of solution in ml

Now put all the given values in the formula of molality, we get

$0.325=\frac{moles\times 1000}{75.0}$

$moles=0.0244$

Therefore, the moles of HCl are 0.0244
