Cobalt Chloride Hexahydrate Molar Mass
Discover the molar mass, M, for cobalt(II) chloride hexahydrate: Thou = sum _iN_im_i Program: • Write the chemical formula and gather atomic masses from the periodic tabular array. • Determine values for N_i and m_i using these items. • Finally, compute the mass. Write the chemical formula: Cl_2CoH_12O_6 Employ the chemical formula to count the number of atoms, N_i, for each element: | N_i Cl (chlorine) | 2 Co (cobalt) | 1 H (hydrogen) | 12 O (oxygen) | vi Look up the diminutive mass, m_i, in chiliad·mol^(-one) for each chemical element in the periodic tabular array: | N_i | m_i/thou·mol^(-one) Cl (chlorine) | 2 | 35.45 Co (cobalt) | 1 | 58.933194 H (hydrogen) | 12 | 1.008 O (oxygen) | 6 | 15.999 Multiply N_i by m_i to compute the mass for each element. And so sum those values to compute the tooth mass, M: Respond: | | | N_i | m_i/one thousand·mol^(-1) | mass/g·mol^(-1) Cl (chlorine) | 2 | 35.45 | 2 × 35.45 = seventy.90 Co (cobalt) | ane | 58.933194 | one × 58.933194 = 58.933194 H (hydrogen) | 12 | ane.008 | 12 × i.008 = 12.096 O (oxygen) | 6 | 15.999 | 6 × 15.999 = 95.994 M = 70.xc m/mol + 58.933194 m/mol + 12.096 g/mol + 95.994 thousand/mol = 237.92 thousand/mol
