A 1000g of sand has been soaked for at least 24hours prior to lab. After drying the sample to saturated surface dry condition, the samples were split into two and put in tare cans. Can1+sample weigh 800g and can2+sample weigh 300g. Can1+sample was used for determining the specific gravity, where volume of water displaced in flask is 320cc. Can2+sample was used for determining the oven-dry weight which resulted to 280g. If the weight of can 1 and 2 is 5g and 6g respectively, determine
