the number is the mass number
the mass number is the number of nucleons (total number of protons and neautrons in the nucleus) so in hydrogen-3 there are 3 nucleons and as hydrogen has 1 proton, there are 2 neutrons
carbon 12 has 12 nucleons (6 protons and 6 neutrons) and carbn 13 has 13 nucleons (6 protons and 7 neutrons)
Answer:
1. Removing them to an area of fresh air. This helps to prevents further poisoning by the carbon monoxide and increase the amount of oxygen entering into the body. This will help to reduce the concentration of carbon monoxide binding oxygen
2. Administering pure oxygen goes a long way to enhance ventilation and increase the oxygen saturation to 100%. This will help to overcome the effect of the carbon monoxide and promote more hemoglobin binding
Answer:
We need 7.94 grams of Ca3(PO4)2
Explanation:
Step 1: Data given
Volume of Ca3(PO4)2 = 200 mL = 0.2 L
Molarity = 0.128 M
Molar mass of Ca3(PO4)2 = 310.18 g/mol
Step 2: Calculate moles of Ca3(PO4)2
Moles = molarity * volume
Moles Ca3(PO4)2 = 0.128 M * 0.2 L
Moles Ca3(PO4)2 = 0.0256 moles
Step 3: Calculate mass of Ca3(PO4)2
Mass Ca3(PO4)2 = moles Ca3(PO4)2 * molar massCa3(PO4)2
Mass Ca3(PO4)2 = 0.0256 moles * 310.18 g/mol
Mass Ca3(PO4)2 = 7.94 grams
We need 7.94 grams of Ca3(PO4)2
