Answer:

96.72 m/min

Explanation:

The following data were obtained from the question:

Time (t) = 56.7 s

Distance (d) = 100 yard

Rate (R) =?

Next, we shall convert 56.7 s to minutes. This can be obtained as follow:

60 s = 1 min

Therefore,

56.7 s = 56.7 s × 1 min /60 s

56.7 s = 0.945 min

Next, we shall convert 100 yard to metre (m). This can be obtained as follow:

1 yard = 0.914 m

Therefore,

100 yard = 100 yard × 0.914 m /1 yard

100 yard = 91.4 m

Finally, we shall determine the rate of the swimmer as follow:

Time (t) = 0.945 min

Distance (d) = 91.4 m

Rate (R) =?

R = d/t

R = 91.4/0.945

R = 96.72 m/min

Thus the rate of the swimmer is 96.72 m/min

An analytical chemist has determined by measurements that there are 8.5 moles of magnesium in a sample of talc. How many moles o
MrRissso [65]

There are 5.66 moles of hydrogen in the sample of talc(hydrated magnesium silicate).

Given,

Talc formula is  Mg_{3} Si_4O_{10} (OH)_2

moles of magnesium = 8.5 moles

The stoichiometry of magnesium and hydrogen is 3 : 2,

So 3 moles of magnesium is equivalent to 2 moles of hydrogen.

Then 8.5 moles of magnesium is equivalent to \frac{2}{3} *8.5=5.6666 moles

<h3>Talc </h3>

Talc(hydrated magnesium silicate), often known as talcum, is a type of clay mineral made up of hydrated magnesium silicate, having the formula Mg3Si4O10(OH)2. Baby powder is made of powdered talc, frequently mixed with corn starch. This mineral serves as a lubricant and thickening agent. It serves as a component in paint, pottery, and roofing materials. It serves as a key component in many cosmetics. It can be found as foliated to fibrous aggregates and in a remarkably uncommon crystal form. It is foliated with a two-dimensional platy form, has a flawless basal cleavage, and an irregular flat fracture.

Talc(hydrated magnesium silicate), the softest mineral, is assigned a value of 1 on the Mohs scale of mineral hardness, which is based on scratch hardness comparisons.

29.2 grams of methane (carbon tetrahydride), CH4, is how
Elena-2011 [213]

Answer:

1.83moles

Explanation:

Given parameters:

Mass of methane given  = 29.2g

Unknown:

Number of moles = ?

Solution:

To find the number of moles in this mass of a compound;

     Number of moles  = \frac{mass}{molar mass}  

Molar mass of CH₄   = 12 + 4(1)  = 16g/mol

Now;

    Number of moles  = \frac{29.2}{16}   = 1.83moles
