What is the mass of 1.75 moles of HF?

Chemistry
1 answer:
olganol [36]3 years ago
7 0

Answer:

Mass = 35.02 g

Explanation:

Given data:

Number of moles = 1.75 mol

Mass of HF = ?

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of HF = 20.01 g/mol

by putting values,

Mass = 1.75 mol × 20.01 g/mol

Mass = 35.02 g

Your answer should have the same number of significant figures is the start of measurement 400.08mL —— L
Eddi Din [679]
The answer would be .40008L

The word milli- translates to \frac{1}{1000} units. In this case, we have liters as our base unit. So a milliliter is \frac{1}{1000} Liters or you can say that there are:

1,000 mL in 1 L. 

As I understand, you are trying to convert 400.08mL to L. 

So this is how you are going to get it:

400.08mL x \frac{1L}{1,000mL}
= \frac{400.08L}{1,000} = 0.40008L

A sample of CH4 is confined in a water manometer. The temperature of the system is 30.0 °C and the atmospheric pressure is 98.70
kakasveta [241]

Explanation:

The given data is as follows.

  P_{atm} = 98.70 kPa = 98700 Pa,  

      T = 30^{o}C = (30 + 273) K = 303 K

      height (h) = 30 mm = 0.03 m (as 1 m = 100 mm)

Density = 13.534 g/mL = 13.534 g/mL \times \frac{10^{6}cm^{3}}{1 m^{3}} \times \frac{1 kg}{1000 g}

                = 13534 kg/m^{3}

The relation between pressure and atmospheric pressure is as follows.

             P = P_{atm} + \rho gh

Putting the given values into the above formula as follows.

            P = P_{atm} + \rho gh

               = 98700 Pa + 13534 \times 9.81 \times 0.03 m

               = 102683.05 Pa

               = 102.68 kPa

thus, we can conclude that the pressure of the given methane gas is 102.68 kPa.
