WebThe mass of the sample of aluminum is calculated as follows - Density = (mass) / (volume) Hence, mass = (density) (volume) …..(1) Volume = 5.90 cm^3. Density = 10.000 g/cm^3. Putting values in the equation (1) - Mass = (10.000 g/cm^3) (5.90 cm^3) Mass = 59 g. Hence, the mass of a sample of aluminum is 59 g. WebObtain a sample of unknown acid from your instructor. Record the sample code of your unknown and the number of reactive (acidic) hydrogen ions (H+ ). Determine the mass … WebThe SI unit for mass is the kilogram (kg), although grams (g) are commonly used in the laboratory to measure smaller quantities. Often, people mistake weight for mass. Weight concerns the force exerted on an object as a function of mass and gravity. This can be written as (1.7.3) Weight = mass × gravity W e i g h t = m g immortals bogowie i herosi caly film
