A pH to one decimal … WebFor example, what is the molar concentration of a solution of 22.4 g of HCl dissolved in 1.56 L? Step 1: First, convert the mass of solute to moles using the molar mass of HCl (36.5 g/mol): 22.4gHCl × 1molHCl 36.5gHCl = 0.614mol HCl. Step 2: Now we can use the definition of molarity to determine a concentration:
WebJul 1, 2024 · The number of significant figures is determined by starting with the leftmost non-zero digit. The leftmost non-zero digit is sometimes called the most significant digit or the most significant figure. For example, in the number 0.004205, the '4' is the most significant figure. The left-hand '0's are not significant. WebNov 7, 2024 · Proper rounding of 28.782 to 3 Significant Digits gives 28.8. With the units, the final answer is 28.8 cm 2.
