Answer: The molar mass of H2S is greater than the molar mass of NH3, making the velocity and effusion rate of NH3 particles faster. Effusion rate is inversely proportional to molar mass.

An element has two naturally-occurring isotopes. The mass numbers of these isotopes are 113 amu and 115 amu, with natural abunda
DENIUS [597]

Answer: Its average atomic mass is 114.9 amu

Explanation:

Mass of isotope 1 = 113 amu

% abundance of isotope 1 = 5% = \frac{5}{100}=0.05

Mass of isotope 2 = 115 amu

% abundance of isotope 2 = 95% = \frac{95}{100}=0.95

Formula used for average atomic mass of an element :

\text{ Average atomic mass of an element}=\sum(\text{atomic mass of an isotopes}\times {{\text { fractional abundance}})

A=\sum[(113\times 0.05)+(115\times 0.95)]

A=114.9amu

Thus its average atomic mass is 114.9 amu

How can you increase the amount of energy in a wave?
patriot [66]

Explanation:

One is amplitude, which is the distance from the rest position of a wave to the top or bottom. Large amplitude waves contain more energy. The other is frequency, which is the number of waves that pass by each second. If more waves pass by, more energy is transferred each second.

2. A lab group turned in their experiment and had measured the mass of their sample
alisha [4.7K]

Answer:

1.61%.

Explanation:

The following data were obtained from the question:

Measured mass = 3.15 g.

Actual mass = 3.10 g

Percentage error =.?

The percentage error of the group can be obtained by using the following equation below:

Percentage error = |Actual mass – Measured mass| / Actual mass × 100

Percentage error = |3.10 – 3.15| /3.10 × 100

Percentage error = 0.05/3.1 × 100

Percentage error = 5/3.1

Percentage error = 1.61%

Therefore, the percentage error of the group is 1.61%.
