An antacid tablet containing 0.50 g of NaHCO3 is dissolved in 250 mL of water. What is the molar concentration of NaHCO3 in the solution? * Molar concentration is solved by determining the molar mass by dividing the amount of solutes to the volume of solution then dividing it to 0.5g. You also need to convert the amount of solutes from grams into moles, and the volume of solution from ml into L In solving the moles of solute, note the NaHCO3, it has 1 Sodium atom, 1 hydrogen atom, 1 carbon atom and 3 oxygen atom. Find its atomic mass according to the periodic table Na=22.99 H=1.008 C= 12.01 O=16.0 Multiply the quantities and add... Atomic mass of NaHCO3= 22.99+1.008+12.01+(16.0×3) =22.99+1.008+12.01+ 48 =84.008 g/ mol Divide it to 0.5 g =0.5g÷ 84.008g/mol =5.951814113^-3 mol Now convert ml to L 250÷1000= 0.25L C=n/v C= =5.951814113^-3 mol/0.25L C= 0.023807256 mol/L or 0.024 mol/L
As a senior high school student, why should you work in a community? WHY SHOULD A SENIOR HIGH SCHOOL STUDENT WORK IN A COMMUNITY? Working in a community is not new already to senior high school students for they have a work immersion as part of their curriculum. Work immersion as part of the senior high school curriculum lets the students experience the real working environment related to their field or track or strand. For me, personally, a senior high school student should work in a community to: prepare himself or herself to the real world setting after graduation help himself or herself to learn practical knowledge beneficial for him or her as he or she will embark to the community real soon. become a contribution to the community and to the country in a bigger perspective Read more here: Objectives of work immersion brainly.ph/question/2643861 Importance of work immersion brainly.ph/question/2490649 Benefits of work immersion brainly.ph/question/2585584 #LetsStudy
