Question

1 A A A 1. What is the mass of a 450 cm block of Silicon if the density of Silicon is 2.336 g/cm stados

Answer 1

Date: 1 1 Solution: Density = 14. mass of 450 cm3 block of silicon = ? Density of silicon - 2.3363|che mass volume (Put values of density and volume as given - In question) - 2.336g66z. mass - 45ocm3 Mass = (2-336gcm) (450 cm) - mass = 1051.2 g or 1.05 kg mass of given silicon block, 1057.29 ox 1.05 kg ||3) for vineges; volume = lome, Valome Melexity = 0.50 m M :0.50 for NaOH, volume Yused - 50 ml; Vz: some 'Molexity of Nach = (m) - Salution - (molarity), * (volime), = (Melesity) + (volumes - My = mava (for vineger) (for NaOH) 60.50m) flome) - Mef some).
