What is the mass in grams of 16.3 mol of the element nickel, Ni?

Chemistry
1 answer:
dangina [55]3 years ago
4 0

Answer:

The mass of 16.3 moles of nickel is 956. 647 g.

Explanation:

Given data:

moles of nickel = 16.3 mol

molar mass of nickel = 58.69 g/mol

mass in gram = ?

solution:

Formula:

number of moles = mass / molar mass

mass = number of moles × molar mass

mass = 16.3 mol × 58.69 g/mol

mass= 956. 647 g

A total of 0.829 L of hydrogen gas is collected over water at 33.0°C. The total pressure is 794 torr.
Natalija [7]

Answer:

P(H₂) = 807.2 torr

Explanation:

According to the Dalton law, the pressure of mixture of a gas is sum of the partial pressure of its mixing component gases.

P(total) = P1 + P2 + P3 +....

In given problem,

Total pressure is = 794 torr

Partial pressure of water = 13.2 torr

Partial pressure of hydrogen = ?

Solution:

P(total) = P(H₂O)  + P(H₂)

P(H₂) = P(total) - P(H₂O)

P(H₂) = 794 torr - 13.2 torr

P(H₂) = 807.2 torr

Which of the following sample will have the greatest average speed at 355 K?. A. CH4. B. Ne. C. C2H4. D. Cl2
Amanda [17]

Answer:

The correct option is methane :CH_4.

Explanation:

Average speed of the gas molecules id given by expression:

v_{avg}=\sqrt{\frac{8kT}{\pi m}}

k = Boltzmann cosnatnt

T = Temperature of the gas molecules = 355 K

m = molecular mass of the molecule

v_{avg}\propto \sqrt{\frac{1}{m}}

Molar mass of methane = 18 g/mol

Molar mass of neon = 20.18 g/mol

Molar mass of ethene = 28 g/mol

Molar mass of chlorine gas = 70 g/mol

Lower the value of molar mass of gas molecule higher will be the average speed.So, from the given options methane gas greatest average seed because it has lowest molecular mass

To determine the concentration of 20.00 mL of an unknown solution of a monoprotic acid, it is titrated with 0.1093 M sodium hydr
Elanso [62]

Answer:

d) 0.1202 M

Explanation:

Let's consider the neutralization reaction between NaOH and a generic monoprotic acid.

NaOH + HA → NaA + H₂O

The used volume of NaOH is 41.63 mL - 19.63 mL = 22.00 mL. The moles of NaOH are:

22.00 × 10⁻³ L × 0.1093 mol/L = 2.405 × 10⁻³ mol

The molar ratio of NaOH to HA is 1:1. The moles of HA that reacted are 2.405 × 10⁻³ moles.

The molar concentration of HA is:

2.405 × 10⁻³ mol / 20.00 × 10⁻³ L = 0.1202 M
