need some help with these questions please?:
34.5g of sodium was reacted with titanium chloride to produce some titanium metal.
TiCl4 + 4Na --> Ti + 4NaCl
a) How many moles of sodium were reacted?
b)how many moles of titanium chloride would have reacted with the sodium?
c) How many moles of titanium chloride would have been produced?
d) What mass of titanium would have been produced if 34.5 tonnes of sodium had been reacted instead?
I think the answer to a is 1.5 moles, because the Ar of Na is 23g so 34.5/23= 1.5

a) You're correct.

b)
Say the equation was something like

2H2 + O2 -> 2H2O

You are told that 2 moles of oxygen were reacted and you need to find out moles of H2. 2 moles of H2 react with one moles of O2 therefore if you had 2 moles of O2, the moles of H2 that reacted would be 4.

c) I think this may be a typo.

d) same thing as b after calculating moles of Na.
