Answer:

251 g of compound contain 2.39 moles.

Explanation:

Given data:

mass of compound Al(CN)3 = 251 g

moles = ?

Solution:

First of all we will calculate the molar mass of given compound.

molar mass of Al(CN)3 = 26.98 + (26 × 3)

molar mass of Al(CN)3 = 105 g/mol

Formula:

number of moles = mass/ molar mass

number of moles = 251 g / 105 g/mol

number of moles = 2.39 mole

If 10.0 mL of the solution on the right are withdrawn from the 100 mL beaker and diluted again in a similar manner, what is the

maks197457 [2]

Answer: 0.050 M NaCl

Explanation:

So the original solution is diluted from a total volume of 10.0 mL to 100.0 mL.

The M represents molarity which is moles of NaCl divided by the total solution volume in liters.

So if our original volume were to be increased by a factor of 10 then the denominator would be changed.

Here is a mathematical illustration:

5/10 = .5

5/100 = .05

Daniel [21]

The best way to display this data for analysis would be a line graph because line graphs are used to track changes over short periods of time. when smaller changes exist. Line graphs can also be used to compare changes over the same period of time for more than one group.

The concentration of protein in a urine sample is calculated to be 2.77 μg/mL. What is the concentration of this solution in uni

maxonik [38]

Answer:

The concentration of this solution in units of pounds per gallon is $2.776*10^{-5} \frac{lb}{gal}$

Explanation:

Units of measurement are established models for measuring different quantities. The conversion of units is the transformation of a quantity, expressed in a certain unit of measure, into an equivalent one, which may or may not be of the same system of units.

In this case, the conversion of units is carried out knowing that 1 μg are equal to 2.205*10⁻⁹ Lb and 1 mL equals 0.00022 Gallons. So

$2.77 \frac{ug}{mL} = \frac{2.77 ug}{mL}$

If 1 μg equals 2.205*10⁻⁹ lb, 2.77 μg how many lb equals?

$lb=\frac{2.77ug*2.205*10^{-9}lb }{1ug}$

lb=6.10785*10⁻⁹

So, 2.77 μg= 6.10785*10⁻⁹ lb

Then:

$2.77 \frac{ug}{mL} = \frac{2.77 ug}{mL}=\frac{6.10785*10^{-9}lb }{mL} =\frac{6.10785*10^{-9}lb }{0.00022 gal} =\frac{6.10785*10^{-9}lb }{0.00022 gal}$

You get:

$2.77 \frac{ug}{mL} = 2.776*10^{-5} \frac{lb}{gal}$

The concentration of this solution in units of pounds per gallon is $2.776*10^{-5} \frac{lb}{gal}$
