An ore of barium contains baco3. a 1.620 g sample of the ore was treated with hcl to dissolve the baco3. the resulting solution was filtered to remove insoluble material and then treated with h2so4 to precipitate baso4. the precipitate was filtered, dried, and found to weigh 0.7766 g. what is the mass of barium in the sample?

just did the assignment and the answer was #1 +2 n

answerto predict;

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
