this question would be nice to copy the melody of 1.0 gram of calcium irons in leader off milk. All right, So what is the formula for the polarity? The solution to polarity is given by the mole divided by the volume and that seemed the mole of a substance can be attained by it, right in the mass by the more mass. So, you know, to determine the polarity, all we need to do this, find our moves and divide by volume. We've been given the mass. The mass. We've been given us 1.0 grams moments of calcium. It is 40.78 According to my period of table grams per mole and a vole, you've been given this one Windsor leaders. So this one sold. He was a very off 2.5 times 10 to the bar, minus two more. The leaders, which is essentially is there a point? There were 25 Moeller
