Stoichiometry Specific gravity on API scale is given by the relation(where, G = specific gravity at 15.5°C). °API = 145 - (145/G) °API = (140/G) - 130 °API = 200(G - 1) °API = (141.5/G) - 131.5 °API = 145 - (145/G) °API = (140/G) - 130 °API = 200(G - 1) °API = (141.5/G) - 131.5 ANSWER DOWNLOAD EXAMIANS APP
