No, a cell's resting membrane potential is typically around -70 millivolts. This negative charge inside the cell is maintained by the sodium-potassium pump, which pumps sodium out and potassium in, creating a voltage difference across the cell membrane.
To determine how many grams of potassium nitrate (KNO3) will settle out when cooling a saturated solution from 70°C to 50°C, you would need the solubility data for KNO3 at both temperatures. Typically, KNO3 is more soluble at higher temperatures, so as the solution cools, some KNO3 will precipitate out. If, for example, the solubility at 70°C is around 120 g/100 g water and at 50°C it's about 85 g/100 g water, then approximately 35 grams of KNO3 would settle out upon cooling. However, you would need the exact solubility values for an accurate calculation.

50-70%
35 pounds is approximately 64% of 55 pounds.
50% of 70= 50% * 70= 0.5 * 70= 35
50% of 70 = 50% * 70 = 0.5 * 70 = 35
70% of 50= 70% * 50= 0.70 * 50= 35
70 + 70 + 50 + 50 = 240
50 percent of 70 of a fraction = 35/150% of 70= 50% * 70= 50/100 * 70= 1/2* 70= 70/2 or 35/1
70 - 50 = 20 So 50 + 20 = 70
70 * 50 = 3,500
50 + 70 = 120
20 + 50 = 70.
Percentage increase from 50 to 70 is (20/50) x 100 = 40% Percentage decrease from 70 to 50 is (20/70) x 100 = 28.5714%
The HCF of 70 and 50 is 10
20 + 50 = 70.
