Calculate the number of Sodium in grams in 7.6 grams of NaCl?
(7.6 g NaCl) (moles NaCl/58.44 g NaCl) (1 mole Na/1 mole NaCl) ( 22.99 g Na/mole Na) = 2.989 g Na or 3.0 g Na (significant figures) Steps: 1. Change everything to moles: use molar mass/molecular of NaCl 2. Find the molar ratio: since there are 1 Na in every NaCl, then the ratio of NaCl to Na is 1:1 3. Change moles back to grams: use the molar mass/molecular weight of Na 4. Watch out for significant figures! I hope this is right
What is the valency of silicate ion?
The valency of the silicate ion is -4, meaning it has a charge of -4. This is because the silicate ion is made up of one silicon atom (which has a valency of +4) and four oxygen atoms (each with a valency of -2).
What is the valency of carbon?
The combining power of carbon is 4. This means that each carbon atom can form 4 bonds.
What is the Valency of sulfur?
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2
What is the valency for silicate radical?
Silicate radical is( SiO4) and its valency is -4
Can you balance the equation TiCl4 plus Na Ti plus Na Cl?
Here is the balanced equation! TiCl4 + 2H2O --> TiO2 + 4HCl

What is the valency for plumbic?
The valency for plumbic is +4. This means that plumbic compounds typically have a charge of +4.
What is valency of tungsten?
the valency is 4
Which element has 4 and 6 valency?
Carbon has a valency of 4, while sulfur has a valency of 6.
What is the valency of silicate?
the valency of silicate ion is 4-
What is the valency of silicate ion?
The valency of the silicate ion is -4, meaning it has a charge of -4. This is because the silicate ion is made up of one silicon atom (which has a valency of +4) and four oxygen atoms (each with a valency of -2).

What is valency of carbon in ethane?
Valency of carbon is 4. It remains 4 in ethane too.
What is the valency of carbon?
The combining power of carbon is 4. This means that each carbon atom can form 4 bonds.
What is the valency of platinum?
Possible valences are (+1), +2, (+3), +4, +6
How do you take out valency an element?
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
