How many moles are in 25 grams of HF

2 answers:

6 0

Suppose 25 L to be 25 kg water (almost, -0.2% at room temperature) then divide 25,000 g by the moalr mass of H2O being 2+16=18 g/mole you get = 1385 moles (because 1 mole = 18 grams)

Using this equation, we can take 25/(1.0 + 19) and find that it is equal to 1.25 moles.

A student obtains a mixture of the chlorides of two unknown metals, X and Z. The percent by mass of X and the percent by mass of

Aleksandr-060686 [28]

<u>Answer:</u> The additional information that is helpful in calculating the mole percent of XCl(s) and ZCl(s) is the molar masses of Z and X

<u>Explanation:</u>

To calculate the mole percent of a substance, we use the equation:

$\text{Mole percent of a substance}=\frac{\text{Moles of a substance}}{\text{Total moles}}\times 100$

Mass percent means that the mass of a substance is present in 100 grams of mixture

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We require the molar masses of Z and X to calculate the mole percent of Z and X respectively

Hence, the additional information that is helpful in calculating the mole percent of XCl(s) and ZCl(s) is the molar masses of Z and X

What is the mass, in grams, of a pure gold cube that has a volume of 4.30 cm3?

umka21 [38]

The density of a pure gold is 19.32g/cm3
if the volume is 4.30 cm3 then we can calculate the mass using the formula mass=density x volume
mass=19.32*4.30
mass=83.076g
