3 0

Answer:

218.09g

Explanation:

the formula for density is mass/volume

you have volume so rlly what you have is 19.3g/cm3=m/11.3cm3

so mass equals density x volume

and 19.3 x 11.3 = 218.09

There are two different compounds of sulfur and fluorine. In SF6, the mass of fluorine per gram of sulfur is 3.55 g F/g S. In th
irinina [24]
For the answer to the question above, <span>1.18 x 3 = 3.55.</span>
<span>First, you need to find the ratio of F to F in each compound. It is the law of multiple proportions stating that the masses of one element which combine with a fixed mass of the second element are in a ratio of whole numbers. In this case, F would be the "one element" and S would be the "fixed mass", the ratio of F6 to Fx = 3:1 </span>
<span>therefore x would be 2 since there is less F in SFx and the ratio is 3:1. divide 6 by 3 and you get 2.</span>

Calculate the volume in milliliters of a 2.09 M silver nitrate solution that contains 400 g of silver nitrate AgNO3. Round your
Liula [17]

<u>Answer:</u> The volume of solution is 1.13 L

<u>Explanation:</u>

To calculate the volume of solution, we use the equation used to calculate the molarity of solution:

\text{Molarity of the solution}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (in L)}}

We are given:

Molarity of solution = 2.09 M

Given mass of silver nitrate = 400. g

Molar mass of silver nitrate = 170 g/mol

Putting values in above equation, we get:

2.09M=\frac{400}{170\times \text{Volume of solution}}\\\\\text{Volume of solution}=\frac{400}{170\times 2.09}=1.13L

Hence, the volume of solution is 1.13 L
