As chief chemist at Superior Analytical Products (SAP) you must design an experiment to determine the density of an unknown liqu

id to three (3) significant figures. The density is of the order of 1 g/cm3. You have approximately 7 mL of the liquid and only graduated cylinders and balances are available for your use. Which of the following combinations of equipment will allow you to meet but not exceed your goal?
a. graduated cylinder with +0.1 mL uncertainty, balance with :0.1g.
b. graduated cylinder with ±001 mL uncertainty: balance with 101 g uncertainty.
c. graduated cylinder with t0.01 mL uncertainty balance with t0 01 g uncertainty.
d. graduated cylinder with ±0 001 mL uncertainty, balance with 10001 g uncertainty.

Answer:

The correct answer is a

Explanation:

The formula for density is mass ÷ volume. Hence, a balance is required to determine the mass while a measuring/graduated cylinder is required to determine the volume.

The ideal measuring cylinder and balance to be used should have an uncertainty of just 0.1 ml and 0.1 g respectively. This reduces the chances of the answer gotten from the formula above to be more than 3 significant figures.

For example, if the volume to be used is 4.0 ml and the mass of this volume is 3.5 g, the density will be

Density = 3.5 ÷ 4

Density = 0.875 g/cm³ or 0.875 g/ml

NOTE that cm³ is the same measurement as mL

The answer above is in 3 significant figures

A sample of a compound is determined to have 1.17 g of carbon and 0.287 g of hydrogen. what is the correct representation of the
yarga [219]

CH3 is the empirical formula for the compound.

A sample of a compound is determined to have 1.17g of Carbon and 0.287 g of hydrogen.

The number of atom or moles in the compound is

1.17 g C X  1 mol of C / 12.011 g C = 0.097411 mol of C.

0.287 g H x 1 mol of  H / 1 g H = 0.28474 mol H.

This compound contains 0.097411 mol of carbon and 0.28474 mol of Hydrogen.

So we can represent the compound with the formula C0.974H0.284.

Subscripts in formulas can be made into whole numbers by multiplying the smaller subscript by the larger subscript.

we can divide 0.284 by 0.0974.

0.284 / 0.0974 = 3.

So here, Carbon is one and hydrogen is 3.

We can write the above formula as a CH3.

Hence the empirical formula for the sample compound is CH3.
