Two of the simplest compounds containing just carbon and hydrogen are methane and ethane. Methane contains 0.3357 g of hydrogen
Natasha_Volkova [10]
Let the ratio of grams of hydrogen per gram of carbon in methane be M, we know that:
M = 0.3357 g / 1 g

Next, lets represent the grams of hydrogen per gram of carbon in ethane be E. The final piece of information we have is:

M / E = 4/3

If we cross multiply,

3M = 4E

Now, substituting the value of M from earlier and solving for E,

E = (3 * 0.3357) / 4
E = 0.2518

There are 0.2518 grams of hydrogen per gram of carbon in ethane.

You have 28.5 g of iron shot that has a volume of 3.60 mL. From this information, calculate the density of iron.
laila [671]

Answer:

\boxed {\boxed {\sf \rho \approx 7.917 \ g/mL}}

Explanation

Density can be found by dividing the mass by the volume.

\rho=\frac{m}{v}

We know the iron sheet has a mass of 28.5 grams and the volume is 3.60 milliliters.

m= 28.5 \ g \\d= 3.60 \ mL

Substitute the values into the formula.

\rho=\frac{28.5 \ g}{ 3.60 \ mL}

Divide.

\rho = 7.91666667 \ g/mL

Let's round to the nearest thousandth.

The 6 in the ten-thousandth tells us to round the 6 to a 7.

\rho \approx 7.917 \ g/mL

The density of iron is about <u>7.917 grams per milliliter.</u>

Grady is doing an experiment about the solubility of sugar. He puts 100 milliliters of water in each of three beakers. He leaves
olga nikolaevna [1]

Grady is doing an experiment about the solubility of sugar. He puts 100 milliliters of water in each of three beakers. He leaves the first beaker at room temperature, heats the second beaker to 60°C, and heats the third beaker until the water boils at 100°C. The variable Grady change on  purpose in the experiment is the temperature of water in each beaker .

Variables in the experiment is the any factor that can exist in different types or amount. There are three types of variables: independent variable , dependent variable , controlled variable. The independent variable is the variable you changed in the experiment. dependent variable is that changes because of independent variable. the controlled variable is the constant one.

Thus, Grady is doing an experiment about the solubility of sugar. He puts 100 milliliters of water in each of three beakers. He leaves the first beaker at room temperature, heats the second beaker to 60°C, and heats the third beaker until the water boils at 100°C. The variable Grady change on  purpose in the experiment is the temperature of water in each beaker .
