Im guessing it might be 98.4x0.58, when you rearrange the pressure formula.
Answer:
Molar mass = (24.31 + 2 × 35.45) = 95.21 g mol–1 i.e. 95.21 g of MgCl2 is exactly 1 mole.
Explanation:
Answer:
Density, 
Explanation:
The attached figure shows a 38.6 kg marble slab. The dimensions of the marble slab is 23 cm × 17 cm × 4 cm
Density = mass/volume
Volume of a cuboid shape is equal to, V = 23 cm × 17 cm × 4 cm
V = 1564 cm³
Density,
or
So, the density of the marble slab is 
.
Answer:
C
Explanation:
For sodium to bond with chlorine, it is through electrovalent bonding.
It means , one electron is transferred from the sodium to the chlorine.
Normally, chlorine has 17 electrons, by adding one , we get 18 electrons.
This is the number of electrons for Argon
The fourth combination is not allowed.
The third quantum number, i.e. m subscript l, only may an integer number from -l to + l. Given that l = 0, the only allowed m subscript l is 0.
