The chemical equation: 2Na3(PO4) + 3Ca(OH)2 ---> 6NaOH + Ca3(PO4)2 If you have 3 moles of Na3(PO4), how many grams of NaOH do you produce?

I WILL give brainiest!!!

Some familiar products contain some of the same types of atoms. for instance, the chemical formula for baking soda is nahco 3. the chemical formula for liquid bleach is naclo, and the chemical formula for table salt is nacl. which choice best describes why these three products have some of the same types of atoms in common?

The chemical composition of soil varies with depth. an article in communications in soil science and plant analysis describes chemical analyses of soil taken from a farm in western australia. fifty specimens were each taken at depths 50 and 250 cm. at a depth of 50 cm, the average no3 concentration (in mg/l) was 88.5 with a standard deviation of 49.4. at a depth of 250 cm, the average concentration was 110.6 with a standard deviation of 51.5. find a 95% confidence interval for the difference in no3 concentrations at the two depths.

What is the concentration, in grams per liter, of a solution prepared by dissolving 0.00040 mol hcl in 2.2 l h2o? assume that the volume of the solution does not change when the hcl is added.
