Answer:
Bacteria
Explanation:
On a piece of raw, fresh hamburger from the butcher's, bacteria are rapidly multiplying through asexual reproduction.
1500 mm of copper wire are produced by converting 150 cm of copper wire.
The following is the centimeter to millimeter conversion factor: 1 cm is equivalent to 10 mm.
Consequently, 150 cm will equal 150 x 10 = 1500 mm.
- The multi-step process of unit conversion involves multiplying or dividing by a numerical factor.
- Unit conversion is the process of converting the measurement of a given amount between various units, often by multiplicative conversion factors that alter the value of the measured quantity without altering its effects.
- Unit conversion is a multi-step procedure that involves adding, subtracting, multiplying, or dividing by a conversion factor.
- The process may also require the selection of the correct number of significant digits, and rounding.

Answer:
26.0 g/mol is the molar mass of the gas
Explanation:
We have to combine density data with the Ideal Gases Law equation to solve this:
P . V = n . R .T
Let's convert the pressure mmHg to atm by a rule of three:
760 mmHg ____ 1 atm
752 mmHg ____ (752 . 1)/760 = 0.989 atm
In density we know that 1 L, occupies 1.053 grams of gas, but we don't know the moles.
Moles = Mass / molar mass.
We can replace density data as this in the equation:
0.989 atm . 1L = (1.053 g / x ) . 0.082 L.atm/mol.K . 298K
(0.989 atm . 1L) / (0.082 L.atm/mol.K . 298K) = 1.053 g / x
0.0405 mol = 1.053 g / x
x = 1.053 g / 0.0405 mol = 26 g/mol
