The scientist's results is that at a temperature of 35<span>°C, the solubility of the substance in water is 146.2 grams in 200 grams of water. There isn't really a different method to determine the solubility of a substance in water. Another procedure could be that a lesser amount of the substance is used and the water required to dissolve it is determined. The solubility of the substance based on the two procedures can then be compared.</span>

4. Does an atom of an element always have the same number of neutrons as other atoms of the same
Sergeeva-Olga [200]

Explanation:

No. Isotopes are atoms of the same element with different atomic masses (due to the different number of neutrons)

For example, carbon exists as carbon-12 and carbon-14, which both have 6 protons but have 6 and 8 neutrons respectively.

What is the mass in milligrams of 4.30 moles of sodium?use âeâ for âÃ10" and use significant figures?
Elis [28]

First, calculate the mass of sodium in g with the help of molar mass and number of moles.

Number of moles = \frac{given mass in g}{molar mass}   (1)

Molar mass of sodium =23 .0 g/mol

Substitute the given value of number of moles and molar mass of sodium in formula (1)

4.30 moles = \frac{given mass in g}{23.0 g/mol}   (1)

4.30 moles\times 23.0 g/mol = mass in g   (1)

mass of sodium in g = 98.9 g

Now, according to conversion factor, 1 g = 1000 mg

So, 98.9 g of sodium = 98.9 \times 1000  mg

= 98900 mg of sodium

Thus, mass of sodium in mg  =9.89 \times 10^{4} mg
