What is calculate the formula weight of ca3 po4 2?
calculate the formula weight of ca3 po4 2 means determining the molecular mass of calcium phosphate by summing atomic contributions of calcium, phosphorus, and oxygen. Laboratories, fertilizer producers, biomedical material teams, and financial analysts who model raw material costs use calculate the formula weight of ca3 po4 2 to quantify inventory, price per mole, and logistics weight.
People often think calculate the formula weight of ca3 po4 2 is approximate, but precise atomic weights and stoichiometry make it exact enough for procurement and dosing. Another misconception is that calculate the formula weight of ca3 po4 2 only matters in chemistry; in reality, budgeting, freight, and compliance documentation rely on accurate masses.
calculate the formula weight of ca3 po4 2 Formula and Mathematical Explanation
The balanced composition Ca3(PO4)2 has 3 calcium atoms, 2 phosphorus atoms, and 8 oxygen atoms. To calculate the formula weight of ca3 po4 2, multiply each atomic weight by its coefficient and sum the results. This delivers grams per mole, which can then be scaled by any mole quantity for inventory planning.
Step-by-step derivation
Step 1: identify atom counts: Ca=3, P=2, O=8. Step 2: apply standard atomic weights. Step 3: compute contributions: 3×Ca, 2×P, 8×O. Step 4: add contributions for the base formula weight. Step 5: multiply by moles to get total batch mass. This is the practical way to calculate the formula weight of ca3 po4 2 without ambiguity.
Variables used to calculate the formula weight of ca3 po4 2
To calculate the formula weight of ca3 po4 2 for a 2.5 mol synthesis, use Ca=40.078, P=30.9738, O=15.999. The base formula weight is 310.176 g/mol. Multiplying by 2.5 moles yields 775.44 g needed. A purchasing manager can now order 0.776 kg of Ca3(PO4)2 for the experiment.
Example 2: Fertilizer shipment budgeting
A fertilizer plant must ship 500 mol of Ca3(PO4)2. Using the same inputs to calculate the formula weight of ca3 po4 2, total mass equals 155,088 g or 155.088 kg. Knowing this mass allows planners to allocate freight space and cost accurately, avoiding underestimating delivery weight.
