shepuryov [24]

Answer:

U= 238g/mol

U2O5= 556g/mol

Explanation:

Since U= 238

O=16

U3O5= 2(238)+3(16)=556g/mol

How do you convert moles to grams?

aniked [119]

Mole is mass (g) / Molar mass (mole/gram)

So to find mass in gram multiply the no.mole by Molar mass

The concentration of CI ion in a sample of H,0 is 15.0 ppm. What mass of CI ion is present in 240.0 mL of H,0, which has a densi

Doss [256]

Answer:

Mass of solute = 0.0036 g

Explanation:

Given data:

Concentration of Cl⁻ = 15.0 ppm

Volume of water = 240 mL

Mass of Cl⁻ present = ?

Solution:

1 mL = 1 g

240 mL = 240 g

Formula:

ppm = mass of solute / mass of sample ×1,000,000

by putting values,

15.0 ppm = (mass of solute / 240 g) ×1,000,000

Mass of solute = 15.0 ppm × 240 g / 1,000,000

Mass of solute = 0.0036 g

Caed for this question.

OLga [1]

Answer:

0.962 atm.

97.4 kPa.

731 torr.

14.1 psi.

97,434.6 Pa.

Explanation:

Hello.

In this case, given the available factors equaling 1 atm of pressure, each required pressure turns out:

- Atmospheres: 1 atm = 760 mmHg:

$p=731mmHg*\frac{1atm}{760mmHg} =0.962atm$

- Kilopascals:: 101.3 kPa = 760 mmHg:

$p=731mmHg*\frac{101.3kPa}{760mmHg} =97.4kPa$

- Torrs: 760 torr = 760 mmHg:

$p=731mmHg*\frac{760 torr}{760mmHg} =731 torr$

- Pounds per square inch: 14.69 psi = 760 mmHg:

$p=731mmHg*\frac{14.69}{760mmHg} =14.1psi$

- Pascals: 101300 Pa = 760 mmHg:

$p=731mmHg*\frac{101300Pa}{760mmHg} \\\\p=97,434.6Pa$

Best regards.
