Explanation: The atomic mass of iron (Fe) is 55.85 amu. The atomic mass of radium (Ra) is 226 amu. One mole of atoms of any element contains 6.022 X 1023 atoms, regardless of the type of element. The mass of one mole of an element depends on what that element is, and is equal to the atom mass of that element in grams.
Mass Molar of

Ca = 3*40 = 120 amu
P = 2*31= 62 amu
O = (16*4)*2 = 64*2 = 128 amu
--------------------------------------
Mass Molar of

= 120 + 62 + 128 = 310 g/mol
Therefore: <span>What is the gram formula mass of Ca3(PO4)2 ?
</span>Answer:
310 grams
Answers:
B, C, and D
Explanation:
B. True. The direction is generally northward, although it turns more to the east off North Carolina (see map).
C. True. The Gulf Stream is an ocean current, because it flows across the Atlantic Ocean.
D. True. It transports warm water from the Gulf of Mexico and the Caribbean towards Iceland and the British Isles.
A. <em>Wrong</em>. The Gulf Stream is <em>not cyclic</em>. It always flows in <em>the same direction, </em>roughly northeast.
Explanation:
momentum increases with an increase in mass and velocity
Answer:
Explanation:
stoichiometry is used in cooking because it helps you determine the amount or proportion of compounds you will need in a chemical reaction. Stoichiometry is present in daily life, even in the cooking recipes we make at home. The reactions depend on the compounds involved and how much of each compound is needed to determine the product that will result.
