You look up the atomic weight for calcium, which is equivalent to the number of grams per mole. Then you divide the 0.85 g by this number, to get the number of moles. From there, it should be easy to convert to millimoles.

How do you convert mmoll to grams for NaCl?
xx mmol x 1 mole/1000 mmol x 58.5 g/mole
Convert mmol to mol?
1 mEq=1 mmol/valence e.g.For sodium, 1 mEq=1mmol/1 (valence of sodium=1) means, 1 mmol sodium=1 mEq of sodium take for calcium,valence=2 1 1 mEq of calcium=1mmol/2=0.5 mmol of calcium
What is the number of grams in 54.9 mmol SO2?
54,9 mmol of sulfur dioxide is equivalent to 3,517 g.
What is the normal reading for calcium in the body?
The serum level of calcium is closely regulated with a normal total calcium of 2.2-2.6 mmol/L (9-10.5 mg/dL) and a normal ionized calcium of 1.1-1.4 mmol/L (4.5-5.6 mg/dL). The amount of total calcium varies with the level of serum albumin, a protein to which calcium is bound. The biologic effect of calcium is determined by the amount of ionized calcium, rather than the total calcium. Ionized calcium does not vary with the albumin level, and therefore it is useful to measure the ionized calcium level when the serum albumin is not within normal ranges, or when a calcium disorder is suspected despite a normal total calcium level.Corrected calcium levelOne can derive a corrected calcium level when the albumin is abnormal. This is to make up for the change in total calcium due to the change in albumin-bound calcium, and gives an estimate of what the calcium level would be if the albumin were within normal ranges.Corrected calcium (mg/dL) = measured total Ca (mg/dL) + 0.8 (4.0 - serum albumin [g/dL]), where 4.0 represents the average albumin level in g/dL. in other words, each 1 g/dL decrease of albumin will decrease 0.8 mg/dL in measured serum Ca and thus 0.8 must be added to the measured Calcium to get a corrected Calcium value.Or: Corrected calcium (mmol/L) = measured total Ca (mmol/L) + 0.02 (40 - serum albumin [g/L]), where 40 represents the average albumin level in g/Lin other words, each 1 g/L decrease of albumin, will decrease 0.02 mmol/L in measured serum Ca and thus 0.02 must be added to the measured value to take this into account and get a corrected calcium.When there is hypoalbuminemia (a lower than normal albumin), the corrected calcium level is higher than the total calcium.
How much sodium bicarbonate would be required to prepare 500ml of a 100mM solution?
500 mL * 100(mMol/mL) = 50 mMol NaHCO3 , hence50 mMol NaHCO3 = 50(mMol) * 84(mg/mMol) = 4200 mg = 4.2 g NaHCO3 in 500 mL
Is it normal to have a normal range of hemoglobin but low red blood cell?
The normal heamoglobin value in human beings are as follows: Men: 13.8 to 18.2 g/dl (138 to 182 g/l, or 8.5 to 10.6 mmol/L) Women: 12.1 to 15.1 g/dl (121 to 151 g/l, or 7.5 to 9.3 mmol/L) Children: 11 to 16 g/dl (111 to 160 g/l, or 6.8 to 9.9 mmol/L) Pregnant women: 11 to 12 g/dl (110 to 120 g/l, or 6.8 to 7.4 mmol/L)
How do you convert 2 moles of calcium to parts per million of calcium carbonate?
2 moles of calcium is 80,156 g; 1 part per million is 1 mg/kg (or L).
Why there is difference between hemoglobin level of human beings and animals?
Here is the information for humans.Men: 13.8 to 18.0 g/dL (138 to 182 g/L, or 8.56 to 11.3 mmol/L)Women: 12.1 to 15.1 g/dL (121 to 151 g/L, or 7.51 to 9.37 mmol/L)Children: 11 to 16 g/dL (111 to 160 g/L, or 6.83 to 9.93 mmol/L)Pregnant women: 11 to 12 g/dL (110 to 120 g/L, or 6.83 to 7.45 mmol/LAnimals are too numerous for the scope of this but I suppose others could add the information on their favorite animals.
What are bone profile values?
The bone profile blood test is a test that measures the amount of calcium, corrected calcium, albumin, total protein and alkaline phosphatase. The normal values are as follows: Calcium (corrected for albumin) 2. 15 - 2. 60 mmol/L, Albumin: 35 - 50 g/L, Total protein: 60 - 80 g/L, and Alkaline phosphatase 30 - 130 U. The above normal limits are for adults.
What mass of NaHCO3 would be needed to neutralize a spill consisting of 12.5 mL of 5.0 M HCl?
12.5 mL * 5.0 (m)mol/(m)L HCl = 62.5 mmol spilled HClneeds62.5 mmol NaHCO3 = 62.5 mmol * 84.01 (m)g/(m)mol NaHCO3 = 5250 mg NaHCO3 = 5.25 g pure NaHCO3
