Answer:
The mass of gas is 30.02 g.
Explanation:
Given data:
Volume of gas = 22.4 L
Density of gas = 1.34 g/L
Mass of gas = ?
Solution:
The given problem will be solved through density formula.
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
Now we will put the values in formula.
1.34 g/L = m /22.4 L
m = 1.34 g/L × 22.4 L
m = 30.02 g
The mass of gas is 30.02 g.
Answer:
closer to F because fluorine has a higher electronegativity than carbon
Explanation:
Electronegativity refers to the ability of an atom in a bonding situation to draw the shared electrons of the bond closer to itself.
Electronegativity increases across the period and decreases down the group. A highly electronegative atom draws the shared electron pair of a bond towards itself.
When two atoms are bonded together, the electron pair is always drawn closer to the atom that has a higher electronegativity.
Hence, the electron pair in a C-F bond could be considered closer to F because fluorine has a higher electronegativity than carbon.
Answer:
the sun goes away and takes heat with it
Explanation:
The density is calculated with the following formula:
density = mass / volume
If there is water on the pan of scale, you will read the mass of the mineral plus mass of water.
Using this value to calculate the density (ignoring the fact that you had water) you will obtain a higher density of the mineral than the real one.
