B. What are the units for the atomic radius?

1 answer:

5 0

Answer:Units used to measure atomic radius: Angstroms (Å): This the most common unit used. Equivalent to 1.0 x 10-10 meters. Nanometer (nm): Equivalent to 1.0 x 10-9 meters.

While in Europe, if you drive 107km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter

Mumz [18]

That's a lot of conversions...
107*7 = 749km in one week
749/1.6 = 468.125 miles
468.125/39 = 12.0032051282 gallons of fuel needed
1 gallon = 4.54609 litres
1.1(Cost per litre)*4.54609(Number of litres per gallon)*12.0032051282(Number of gallons needed) = 60.0244158814 euros cost per week
60.0244158814 * 1.26 = 75.6307640105 dollar cost per week
$75.63

Elements are identified by the number of

Papessa [141]

The simplest way to use the periodic table to identify an element is by looking for the element's name or elemental symbol. The periodic table can be used to identify an element by looking for the element's atomic number. The atomic number of an element is the number of protons found within the atoms of that element.

Determine the molar mass of a 0.314-gram sample of gas having a volume of 1.6 l at 287 k and 0.92 atm. show your work.

Olenka [21]

As per Ideal gas equation, molar mass of the gas is 5.032 g/mo

We’ll begin by calculating the number of mole of the gas. This can be obtained as follow:

Volume (V) = 1.6 L

Temperature (T) = 287 K

Pressure (P) = 0.92 atm

Gas constant (R) = 0.0821 atm.L/Kmol

Number of mole (n) =?

According to Ideal gas equation , PV = nRT

0.92 × 1.6 = n × 0.0821 × 287

1.472 = n × 23.5627

Divide by 23.5627

n = 1.176 / 23.5627

n = 0.0624 mole

Finally, we shall determine the molar mass of the gas. This can be obtained as follow:

Mass of gas = 0.314 g

Number of mole = 0.0624 mole

Mole = $\frac{mass}{molar mass}$

0.0624 = $\frac{0.314}{molar mass}$

Cross multiply

0.0624 × molar mass of gas = 0.314

Divide by 0.0624

Molar mass of gas = $\frac{0.314}{0.0624}$

Molar mass of gas = 5.032 g/mo

Therefore the Molar mass of gas is 5.032 g/mo
