I need help in writing chemical equations.

I can get the mathematical equations down right, but the text part of the chemical equation is where I am having trouble.

ex.

(1,000 Lbs NaCl) (0.0044 Lbs H2 / 0.2577 Lbs NaCl) = 17.0771 Lbs H2

I need to add spaces in the text part.

Other wise it looks like 0.2577LbsH2 { the 2 is super script}

Or is this the best the Equation Editor can do and I am left not using it?

Any help and insight will be most helpful
