The density of urine decreases when a diabetic secretes too much sugar.

When there is excess sugar in the blood, the kidneys release extra water.

The result is a more dilute and therefore less dense urine.

The urine from a non-diabetic person usually has a density of 1.010 g/mL to 1.025 g/mL.

The urine from a diabetic person often has a density less than 1.008 g/mL.

How many grams of a 22.9% sugar solution contain 68.5 g of sugar?

777dan777 [17]

The grams of 22.9 % sugar solution that contain 68.5 g of sugar is 299.13 g of solution

calculation

22.9% means that there are 22.9 g of sugar in 100 g of solution.

what about 68.5 g of sugar

- by cross multiplication

=[(68.5 g sugar x 100 g solution) /22.9 g sugar] =299.13 g of solution

Nb; g sugar cancel each other

A sodium hydroxide solution is made by mixing 8.70 g NaOH with 100 g of water. The resulting solution has a density of 1.087 g/m

Ahat [919]

Answer:

Mass fraction = 0.08004

Mole fraction = 0.0377

Explanation:

Given, Mass of NaOH = 8.70 g

Mass of solution = 8.70 + 100 g = 108.70 g

$Mass\ fraction\ of\ NaOH=\frac {8.70}{108.70}$ = 0.08004

Molar mass of NaOH = 39.997 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{8.70\ g}{39.997\ g/mol}$

$Moles\ of\ NaOH= 0.2175\ mol$

Given, Mass of water = 100 g

Molar mass of water = 18.0153 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{100\ g}{18.0153\ g/mol}$

$Moles\ of\ water= 5.5508\ mol$

So, according to definition of mole fraction:

$Mole\ fraction\ of\ NaOH=\frac {n_{NaOH}}{n_{NaOH}+n_{water}}$

$Mole\ fraction\ of\ NaOH=\frac {0.2175}{0.2175+5.5508}=0.0377$

What ions will form when baking soda is dissolved in water?

ad-work [718]

Answer:When you add baking powder to water or milk, the alkali and the acidreact with one another and produce carbon dioxide – the bubbles. Sodium bicarbonate is a weak base which is commonly known as baking soda and used in cooking. It weakly ionizes in water: NaHCO3 + H2O → H2CO3 + (OH-) + (Na+). u need to stop deleteing my answers ughh
